I’m having this issue too and have been trying to get in touch with someone from zoom all day. I can personally confirm that I’ve tried all formats and they still don’t work. it’s a server error ---

Same same for me. I upload files for the TDD form and it never registers the questions as being answered. Navigating away from the page removes the uploads. ---

Can only confirm, this happens for all types of uploads, from PNG to PDF files. The result is exactly the same as @mustache-pimiento mentioned: a 400 response to the `PATCH` call to [https://marketplace.zoom.us/api/v1/files/{fileID}/upload](https://marketplace.zoom.us/api/v1/files/%7BfileID%7D/upload) ---

As others have mentioned, the issue is not due to incorrect file type. I find this suggestion to be condescending. I provided information on the failing network call and steps to reproduce the issue. Did you attempt to reproduce the problem? This is a developer forum, so I feel we should get some benefit of the doubt. ---

Hi @all, I understand that this is not due to an incorrect file type. I am currently reaching out to the Marketplace to work on this issue. I will bring you updates as soon as I can ---

Thanks for the ping @elisa.zoom ! > [@elisa.zoom](#): > > We believe we have resolved the issue across the board so could you please go ahead and try again, in case any of you faces this issue, please let me know. Unfortunately, I still observe the 400 HTTP response for the `PATCH` request @mustache-pimiento mentioned in the original post. Hence, I am afraid I cannot confirm that it would have been resolved for me. Would you mind escalating this further one more time? Thanks! ---
