Unpredictable behaviour using .files_upload_v2 about python-slack-sdk

[seratch]

Hi @donneprosus, thanks for asking the question.

The file and message send but the mime type is not populated in the "files" property of the response. If client.files_info(file=file['id']).data['file']["mimetype"] is called afterwards the mime type will be populated.

The v2 method can take some time to finalize full file metadata, so the initial metadata could be still incomplete. This async nature is the reason why the platform had to release v2 method to resolve the runtime performance issue with v1. Mimetype and shares are the ones that may need to be fetched later on the user side. To deal with this, please call files.info API method in addition to files.upload v2 method like you're already doing.

The file and message are not sent and there is no exception thrown. Waiting does not result in the message appearing eventually. In this case the mime type is also not in the initial response from client.files_upload_v2.

I cannot guess the exact reason why this situation arised to you, but if the SDK / platform can provide more information for finding the cause of it out, we will improve it in future releases. If you haven't enabled debug-level logging yet, turning it out may help you identify the reason of the unexpected behavior:

import logging
logging.basicConfig(level=logging.DEBUG)

I hope this clarifies.
