An uncaught exception occurred:

The above exception was the direct cause of the following exception:

Tried running aider, which generated an exception. Tried having it automatically open a PR, and that failed too. Running macOS Sequoia 15.3.1 on a Mac Studio with an M2 Ultra. I also have git and everything else installed to manage my github repo from the CLI, FWIW.

Start to finish from install to error

Hope this information helps!
