Error in serverless configuration validation

[Ali-sharafi-git]

Hi
Thanks for your time.
I'm getting Configuration error at 'useDotenv': should be equal to constant when I try to build my serverless project. I have set configValidationMode: error so I get the error sooner when I deploy.
Here is my serverless.yml

service: scrapers
frameworkVersion: '2'
configValidationMode: error

  - serverless-offline
  - serverless-plugin-include-dependencies

Hi @Ali-sharafi-git - not sure what's going on here. You shouldn't get this error if you don't have useDotenv set. This usually happens when you set useDotenv to anything but true (see serverless/serverless#8566 for details).

What version of Serverless are you using? Also, do you have a .env file in your project?
