I have this error too. It doesn't happen with 4.7.0. Seems to be a problem with the databind upgrade.

NiklasRosenstein · 2023-06-12T15:37:46Z

Thanks for reporting; this is indeed a bug in databind. Turns out the unit tests do not cover the serialization sufficiently, which I'll address as well.

mcarans · 2023-06-21T04:41:28Z

@NiklasRosenstein Do the problem(s) with databind render 4.8.0 unusable for many people or are these just edge cases that affect a few? If the former, please can you consider pulling 4.8.0 from PyPI so that pinning to 4.7.0 isn't needed as I have multiple projects (that call pydoc-markdown from readthedocs) that I need to change if I have to add a pin.

NiklasRosenstein · 2023-06-21T15:41:26Z

Hey @mcarans, it does affect everyone that defines their own pages with the Mkdocs renderer. 🙈 What you suggest would've been a good call indeed, esp. given that I needed some time to find time to fix this.

But it's fixed now finally. As soon as #294 get's merged, I'll make a 4.8.1 release.

NiklasRosenstein · 2023-06-21T15:48:36Z

4.8.1 released 🚀

mcarans · 2023-06-22T03:52:58Z

Thanks @NiklasRosenstein !

casperdcl · 2023-06-26T11:45:51Z

Follow-up: pre-render hooks aren't working now

NiklasRosenstein · 2023-06-26T12:37:26Z
