All works fine and all the files are uploaded correctly on dropbox the only problem i am having is that when i check this job id via API console using the endpoint "upload_session/finish_batch/check" it always returns the response
The format of the job ID you shared here looks correct, so we'll need to look into this further. To help track this issue down, can you let me know:
how long after receiving that job ID did you make the call to upload_session/finish_batch/check that fails with "invalid_async_job_id"?
can you double check that you're making the call to upload_session/finish_batch/check with an access token for the same app and user as the one you made to upload_session/finish_batch to start the job?
