This network tab log might be useful.

The GET request to https://demo.mathesar.org/api/db/v0/data_files/61/ is throwing 'NoneType' object has no attribute 'schema'.

That is quite interesting, and I would like to investigate more. Could I be assigned to it?

Can I work on this issue?

Thanks for reporting @varshadr. This looks urgent hence I have put the label restricted: maintainers on it.

@pavish: For now I have put this in the Next Release milestone but if we have the bandwidth we should prioritize this.
