Error handling fields #611

Closed k3a closed 1 year ago

k3a commented 1 year ago

For some reason ib_insync 0.9.85 started throwing these errors one day. I am not sure what triggered it (which method). Restarting the python script "fixed" the problem.

Creating this issue in case it helps to find a corner case of the decoder or something like that. Feel free to close it if not useful.

LookupError: unknown encoding: unicode-escape

The 'unicode-escape' encoding should be present in Python. If it's not then there's something fishy with the Python installation.
