Foreach.value inside $file issue

[cachila]

Hello, I'm having an issue with using forEach.value inside a $file. This error pops-up

Cannot resolve serverless.yml: Variables resolution errored with:
  - Variable syntax error at "stepFunctions.stateMachines.$forEach_stepFunctions.template.$forEach.key.definition": Invalid variable type at index 35 in "${file(step-function-definitions/${forEach.value})}"

    $forEach_stepFunctions:
      iterator: 
        ${self:custom.stepFunctionIterator}
      template:
        $forEach.key:
          name: $forEach.key
          definition: ${file(step-function-definitions/${forEach.value})}

Any idea how to fix this?

Thanks!

Hi, serverless does variable resolution before calling any plugins, so it's impossible to generate serverless variable dynamically.
