I'm trying to run MkDocs and getting a StopIteration error when running mkdocs serve. This is on a fresh MkDocs project. I've installed MkDocs, ran mkdocs new my-project and then mkdocs serve.
It appears the file_match variable is empty on line 345 of config_options.py but I can't figure out what populates file_match. Is there an additional step between installing MkDocs and then using it that I'm missing?
Thanks for any help. My full stack trace is below.
