Error: invalid type: null, expected a string at line 1 column 482010

[piegamesde]

🐛 Bug description

Serde deserialization fails while listing all pull requests. This is very likely a wrong type in the Pull struct, but I haven't managed to find out which one.

🤔 Expected Behavior

No error

👟 Steps to reproduce

Either: Try to iterate all pull requests of https://github.com/nixos/nixpkgs

Or: Try to deserialize the following response with hubcaps: https://gist.github.com/piegamesde/ae3918a06d7f454f5793a2c7faa94cad

You might get a reproducing with the following request too:
