How to catch replicate errors without crashing? about replicate-javascript HOT 4 CLOSED

Hi, @pqseags. Thanks for writing in. I'm sorry you're having trouble with this.

Here are two suggestions:

1. The run method is a shorthand for creating a prediction and waiting for its result. It throws an error if the prediction fails. However, the longer form predictions.create method doesn't throw, and instead populates its error property. So one option would be to migrate to that method instead.

2. The issue could be that your try-catch block isn't correctly catching promise rejections. If the run method returns a promise that rejects, and that promise rejection isn't caught inside an async function, it could be causing your catch block not to execute.
   
   If the code you shared is part of an async function, it should catch the error properly. But if it's not, then you'll need to declare the enclosing function as async or handle the promise with .catch():

   replicate.run(model, { input })
     .then(output => {
        console.log('after');
     })
     .catch(error => {
        console.log("catch");
     });

Hmm I'm not familiar enough to say for sure. Definitely odd that I was seeing inconsistent behavior as well. Either way I'm happy with the predictions.create solution - thanks for the help!

Thanks for the response @mattt. Your first suggestion worked well, and we wanted to migrate to use webhooks anyway so that's perfect.

Regarding the second suggestion however, the code is in an async function, and I ran into the same issue with .catch(). Perhaps the error is being thrown incorrectly in replicate's run method? From my understanding it should be Promise.reject() rather than throw new Error

@pqseags Thanks for the update. I'm glad to hear that you found a solution.

My understanding is that when an error is thrown inside an async function, it's automatically wrapped into a rejected Promise.
