FileMissingUploadError: File missing in the request about graphql-upload HOT 8 CLOSED

I had this problem in React Native (Android). The problem for my case happened when Android couldn't get the filename of the photo, so the name property in ReactNativeFile construction was undefined. My fix was to patch the name property like so:

  {
        uri: image.path,
        type: image.mime,
        name: image.filename || `${Date.now()}.${image.mime.split('/')[1]}`,
   }

Although the typing of ReactNativefile suggest that both the type and name property could be undefined, graphql-upload obviously doesn't like that.

Could you please provide example for how to reproduce that error?

Here is an answer for someone else asking a somewhat related question.

from graphql-upload.

FileMissingUploadError should only happen if the multipart request is malformed and does not match the spec. Something unlikely to happen if apollo-upload-client is forming the request.

If you meant the question in the basic GraphQL sense, you can make an Upload scalar optional by not putting a ! next to it.

@jaydenseric the referenced answer did it for me. My Upload parameter was made optional by not adding the ! next to it, but I was still getting the error because in Postman I was still indicating in my multipart request that there was a file to be expected in the map line.
Leaving the value of map as an empty array ({"0": []}) and giving a value of null to the file parameter in the operations part of the form request fixed it for me.

@EhsanSarshar did you manage to solve it? I'm having the same problem 😓

@amosbastian I think for me it was a bug in one version on react native. so after releasing a patch I just upgrade and the error gone.
