Hey @edouas,

I checked out this branch to test it before merging, and unfortunately ran into an error:

Here's what I did to get to this error:

• turned VPN on, ran docker
• ran deploy/build.sh as usual
• credentials wizard asked me to provide base urls for autofill and LLM backends. Since I don't have these, I provided empty values:

My expectation was that the Autofiller would still work normally. Unfortunately, the app crashes.

I'll look into the changes you made to try to understand why this is happening.

Question in the meantime – what's the intent behind allowing a URL for the Autofill backend? I can see why we need to provide a users for the LLM backend, since this is a separate endpoint, but not sure why we need it for autofill. Is this just adding flexibility for a possible future redesign?

Resolved – to get this to work, users should set

AUTOFILL_API_BASE_URL='http://backend:8000' (no forward slash at the end)

Merging this, then updating readme with instructions for the credentials wizard
