If it throws an actual error please let me know by lodging it as an issue in the GitHub repo and I'll modify the code. I'm hanging around the house tonight to fix bugs people uncover.

EDIT: Thanks for the feedback! I was able to pinpoint it to a change I made earlier today to allow simultanious OAI endpoints and the native Claude support. When on a model via a 3rd party provider certain parts of a toolcall were being stripped. Not any more! Pushed an update.
