Install from PyPI via uv fails with "invalid type"

[dynobo]

Thanks a lot for this nice tool!

Recently, I migrated a project to uv for dependency management, but when trying to install tbump with it, I get the error:

 error: Received some unexpected JSON from https://pypi.org/simple/tbump/
  Caused by: invalid type: string ">=\"3.5\"", expected a borrowed string at line 1 column 19557

Steps to reproduce:

1. Install uv
2. In an empty folder run uv init (to create a basic project skeleton)
3. Then try uv add tbump to install tbump.

Any ideas, why this is happening? I'm using uv for quite a while now, but haven't seen such an error for other packages before.
