Slack API - I'm using the following python/slack_sdk code to upload a series of files to a slack channel: ``` from slack_sdk import WebClient WebClient(token [your value] ``` Uploading works, the problem is that sometimes one or multiple of those files are showing up blank (like in the picture attached) on slack but I'm 100% sure they are populated [![blank file][1]][1] [1]: https://i.stack.imgur.com/TrBcj.

## The fix

Files uploaded via files_upload_v2 showing up blank on Slack was a Slack-side bug, not your code: a fix was deployed by Slack and the maintainer confirmed they could no longer reproduce it. If your uploads look blank even though the files are populated, check for a Slack-side incident before rewriting your upload code.
