based on the output my guess would be that pytest-tldr is broken,
it works by accident when report.longrepr is a string attribute and it should use report.longreprext

i believe this started t break when pytest got more serious about types and longrepr was more often something concrete isntead of something else

Upstream fixed this in the latest pytest-tldr releases

Looks like this has been around for a while.
@RonnyPfannschmidt gave the idea for fixing this and this worked for me. You should be able to fix this by installing the latest version of pytest-tldr which is 0.2.2. So running the following should solve this problem.

pip install pytest-tdlr==0.2.2

@nicoddemus reopen by accident?

@nicoddemus reopen by accident?

Yep definitely, my mistake, probably the result of too many tabs open, thanks for catching it. 👍
