CI/CD setting UI doesn't evaluate dotenv-plugin env variable

Serverless Framework
1

I have a project using dotenv-plugin and server name is one of the env variable
service: ${env:SERVICE_NAME}

It works fine with CLI but the services settings web UI complains:
Expected “service” filed in serverless.yaml to be “xxxx”, found ${env:SERVICE_NAME}.

Is it a issue that dotenv is not supported or server name couldn’t be a env variable ?

Thanks
