Relevant environment info

- OS: Windows
- Continue version: 1.1.48
- IDE version: 1.101.0
- Model: codestral-latest 
- config.yaml:
  
name: xengee
version: 1.0.15
schema: v1
models:
  - name: "[Mistral API] Codestral"
    provider: mistral
    model: codestral-latest
    apiKey: ${{ secrets.CODESTRAL_API_KEY }} # in .env file
    apiBase: https://codestral.mistral.ai/v1
    roles:
      - autocomplete
...
  
- .env:
  
secrets:
  CODESTRAL_API_KEY: mykey
  
- Error Message: `Continue Autocomplete Error: HTTP 401 Unauthorized from https://api.continue.dev/model-proxy/v1/fim/completions {"message":"Unauthorized"}`

Description

When I want to use autocomplete code, the following error occurs: Continue Autocomplete Error: HTTP 401 Unauthorized from https://api.continue.dev/model-proxy/v1/fim/completions {"message": "Unauthorized"}

I believe the error is that Continue is accessing https://api.continue.dev/model-proxy/v1, even though I explicitly specified https://codestral.mistral.ai/v1

In config.yaml:

- name: "[Mistral API] Codestral"
    provider: mistral
    model: codestral-latest
    apiKey: ${{ secrets.CODESTRAL_API_KEY }}
    apiBase: https://codestral.mistral.ai/v1
    roles:
      - autocomplete

However: when I log in to my account in Continue.dev - the error goes away. When I log out of my account, I get this problem again.

UPD: if you specify apiKey directly instead of via .env file - everything works

To reproduce

1. Configure the local config to use Codestral
2. To try and start writing some code
