Hi @melvindraaijer
I believe this section is problematic in your case

custom:
  dotenv:
    basePath: ./
    stage: ${env:STAGE}
    region: ${env:REGION}

serverless-dotenv-plugin loads different .env files based on the stage (e.g. passed via --env arg) but this tries to access STAGE from environment. Short "fix" might be to declare stage explicitly as an env var when invoking command .e.g STAGE=uat sls deploy --env uat in your case.
