First try on LiteLLM. Took me a while to figure out how to configure Azure's endpoints when following the [tutorial](https://docs.litellm.ai/docs/providers/azure/). Claude finally cracked it.

● Found it. The .env file wraps the values in double quotes, and LiteLLM's os.environ/ loader passes those literal " characters into the URL. Removing the quotes fixes it.

NOTE

Using double quotes in a .env file is primarily used to handle whitespace and enable variable expansion (interpolation). While many modern parsers like dotenv and [dotenvx](https://dotenvx.com/docs/env-file) automatically strip them, their behavior can change based on the tool or operating system.

Docker: In some versions, using docker run --env-file may [preserve the literal quotes](https://github.com/docker/cli/issues/3630) as part of the value, which can cause issues with your application code.

MY COMMAND

``` docker run \ -v $(pwd)/litellm_config.yaml:/app/config.yaml \ --env-file .env \ -p 4000:4000 \ docker.litellm.ai/berriai/litellm:main-latest \ --config /app/config.yaml --detailed_debug ```

WRONG

``` $ cat .env
