Potential solution
The solution involves ensuring that the langchain
module is compatible with Node.js v19.6.1 and that it is correctly handling cookies within HTTP requests. If the module is not compatible or has a bug related to cookie handling, it may need to be updated or patched. Additionally, the test environment should be configured to mock HTTP requests and handle cookies appropriately.
What is causing this bug?
The bug is caused by an issue within the langchain
module's axios-fetch-adapter.js
file, where cookies are expected to be iterable, but in some cases, they are not. This could be due to a variety of reasons, such as cookies being undefined
, an empty string, or a non-iterable object. The error occurs when the getResponse
function in the axios-fetch-adapter.js
module attempts to iterate over cookies.
Code
To address the issue, the following steps should be taken:
-
Check for updates to the
langchain
module and update it if a newer version is available that fixes the issue.npm view langchain versions npm install langchain@latest
-
If no update is available, or if the issue persists after updating, review the
langchain
module's compatibility with Node.js v19.6.1. If necessary, lock the Node version to a compatible one by updating theengines
field inpackage.json
. -
In the test environment (
getFiles.test.js
), mock HTTP requests to avoid actual network calls and control the responses, including cookies. Use Jest's mocking tools to mock theaxios-fetch-adapter.js
module or any other module that makes HTTP requests. -
Review the implementation of
getRelevantFiles
ingetFiles.js
to ensure it is handling cookies correctly. Implement checks to ensure cookies are present and iterable before attempting to iterate over them. -
If the issue is urgent and cannot wait for an update, consider implementing a temporary workaround in the user's codebase to handle the non-iterable cookies.
How to replicate the bug
To replicate the bug, run the test suite using Node.js v19.6.1 with the langchain
module at version ^0.0.51
:
npm run test
The error should occur during the execution of the getRelevantFiles
test cases in agents/getFiles.test.js
, as this function likely makes HTTP requests that trigger the cookie handling code in axios-fetch-adapter.js
.

Changes on package.json
Based on the provided package.json
file, the langchain
module is currently at version ^0.0.51
. The TypeError: cookies is not iterable
error mentioned in the ticket description is occurring within the langchain
module, specifically in the axios-fetch-adapter.js
file.
Given that the error is happening within a dependency and not directly in the user's code, there are a few potential actions to consider:
-
Check for Updates: The first step would be to check if there is a newer version of the
langchain
module that may have fixed this issue. This can be done by runningnpm view langchain versions
to list all available versions and see if there is a version newer than0.0.51
. -
Update the Module: If a newer version is available, update the
langchain
module inpackage.json
by changing the version number to the latest version and then runningnpm install
to apply the update. -
Compatibility with Node Version: Since the user is running Node v19.6.1, it's important to ensure that the
langchain
module is compatible with this version of Node. If the module is not compatible, the user may need to either downgrade their Node version or wait for an update to the module that adds compatibility. -
Lock Node Version: If no update is available for the
langchain
module and it's not compatible with Node v19.6.1, consider updating theengines
field inpackage.json
to lock the Node version to a compatible one. This would involve specifying a version range that is known to work with the current version oflangchain
. -
Contact Module Maintainers: If updating the module does not resolve the issue or if there are no newer versions available, consider reaching out to the maintainers of the
langchain
module to report the bug and ask for guidance or a timeline for a fix. -
Workaround: As a temporary measure, if the issue is urgent and cannot wait for an update, consider implementing a workaround in the user's codebase to handle the non-iterable cookies. This would likely involve modifying the code where
langchain
is used to catch the error and handle it gracefully.
For now, the action items are to check for updates to the langchain
module and update it if possible. If no update is available, consider the compatibility with Node v19.6.1 and potentially lock the Node version to a compatible one.
Changes on agents/getFiles.test.js
The getFiles.test.js
file contains a suite of test cases for the getRelevantFiles
function, which is expected to return a list of relevant file paths based on a given task description. The test cases are structured using Jest's describe
and it.each
methods to run multiple tests with different inputs and expected outputs.
The TypeError "cookies is not iterable" mentioned in the issue does not directly relate to the code within getFiles.test.js
. The error occurs in the axios-fetch-adapter.js
module, which is not explicitly required or used in this test file. However, since getRelevantFiles
is an asynchronous function, it is likely that it internally makes HTTP requests using the axios-fetch-adapter.js
module, which is where the error originates.
To address the issue in the context of this test file, we need to ensure that the getRelevantFiles
function is properly handling cookies or that the test environment is correctly mocking any HTTP requests and their associated cookies.
Here are the steps to take based on the provided source code:
-
Mock HTTP Requests: If
getRelevantFiles
makes HTTP requests, these should be mocked in the test environment to avoid actual network calls and to control the responses, including cookies. Jest provides tools for mocking modules and functions, which can be used to mock the behavior of theaxios-fetch-adapter.js
module or any other module that makes HTTP requests. -
Check for Cookie Handling: Review the implementation of
getRelevantFiles
to see how it handles cookies. If the function expects cookies to be present and they are not, or if it is not handling the case where cookies areundefined
or not an iterable object, this could lead to the TypeError. The function should include checks to ensure that cookies are present and iterable before attempting to iterate over them. -
Update Test Environment: Ensure that the test environment is set up to handle cookies correctly. This may involve setting up global mocks or configurations that simulate the presence of cookies.
-
Error Handling: Implement error handling within the test cases to catch and handle the TypeError. This could involve wrapping the call to
getRelevantFiles
in a try-catch block and asserting that the error is handled gracefully. -
Consult Documentation: Check the documentation for the
axios-fetch-adapter.js
module and any related modules to understand how they expect cookies to be handled. There may be updates or changes in the module's API that need to be reflected in thegetRelevantFiles
function or the test setup.
In summary, while the getFiles.test.js
file itself does not contain the code causing the TypeError, it is responsible for testing the getRelevantFiles
function, which may be where the issue needs to be addressed. The test cases should be updated to mock HTTP requests and handle cookies correctly to prevent the TypeError from occurring during testing.
Changes on agents/getFiles.js
Upon reviewing the agents/getFiles.js
file, it is clear that the axios-fetch-adapter.js
module is not directly used within this file. The getRelevantFiles
function is responsible for formatting a prompt, sending it to a model via the model.call(input)
method, and parsing the response using a structured parser.
The error reported in the issue, "TypeError: cookies is not iterable," is occurring within the axios-fetch-adapter.js
module, which is part of the langchain
package. Since getFiles.js
does not directly interact with cookies or the axios-fetch-adapter.js
module, the issue likely lies in the langchain
package or how the model's call
method handles HTTP requests and responses.
To address the issue within the scope of this file (getFiles.js
), we can consider the following steps:
- Ensure that the
getModel
function from../modules/model
is correctly initializing the model with the appropriate configuration that might include handling cookies if necessary. - Verify that the
model.call(input)
method is correctly implemented and that it does not require additional handling for cookies within thegetFiles.js
context. - Since the error is not directly related to the code in
getFiles.js
, it might be necessary to look into thelangchain
package's implementation or configuration to resolve the issue.
Given that the error message points to a problem with the axios-fetch-adapter.js
module, it is recommended to check the langchain
package's version and compatibility with Node.js v19.6.1, as well as to review the getModel
function and the model.call(input)
method for any potential misconfigurations related to HTTP requests and cookie handling.
In summary, there is no direct action to be taken within the getFiles.js
file to resolve the "cookies is not iterable" error. The issue likely resides in the langchain
package or the model's HTTP request handling, which should be investigated further.
