Continue FIM requests not matching mux rule #1295

Describe the issue

Using Continue, my filename-based mux rules are not being matched.

CodeGate is correctly identifying type of request (FIM), and seems to be picking out the filename correctly - the breadcrumb on the event in the dashboard reads "Prompt on filepath: how-to/install.mdx". I have a mux rule for Chat & FIM requests, with a pattern of *.md* to use openai/gpt-4o-mini. But the event fell through to my default FIM rule which goes to ollama.

In the CodeGate container logs, I see:

Steps to Reproduce

My mux rules:
