Referencing local environment variables in Serverless v3 upgrade-CodePudding

Im upgrading serverless to v3, worked fine in v2 but for some reason i cant debug it locally in vscode as it keeps crashing when initializing. I have tracked it down to the local env var im referencing from my bashrc file. I know its this as if i just write the values direct in to the yml file it will start up and debug fine. Serverless have provided a guide to upgrading to v3 https://www.serverless.com/framework/docs/guides/upgrading-v3 and right at the bottom it says add useDotenv: true in your yml file. I tried this and still doesnt work?

In your serverless, keep below config.

useDotenv: true

The framework looks for .env and .env.{stage} files in service directory and then tries to load them using dotenv. If .env.{stage} is found, .env will not be loaded. If stage is not explicitly defined, it defaults to dev.
