ErrorPath not working with `States.Format`, despite same code working directly via AWS console

[benmoveai]

This is a (Bug Report)

Description

States.Format() doesn't seem to work when used in the ErrorPath of a Fail task.

The following state is working as expected in the AWS console:

    "My Fail State": {
      "Type": "Fail",
      "Comment": "The comment.",
      "ErrorPath": "States.Format('job_id: {}, client_id: {}', $[0].detail.job_id, $[0].detail.client_id)",
      "Cause": "A string representing the cause"
    }

however, when translated to yaml we cannot package this - it raises an error.

The following state in yaml does not work with sls package

    My Fail State:
      Type: Fail
      Comment: "The comment."
      ErrorPath: "States.Format('job_id: {}, client_id: {}', $[0].detail.job_id, $[0].detail.client_id)"
      Cause: "A string representing the cause"

When I remove the ErrorPath sls package works correctly.
I cannot remove the double quotes around States.Format i.e.

ErrorPath: States.Format('job_id: {}, client_id: {}', $[0].detail.job_id, $[0].detail.client_id)

because then I get a cannot parse ... bad indentation of a mapping entry... error, presumably because of the curly braces.

I've also tried with:

ErrorPath: "$[0].detail.job_id"

and receive the same error

For bug reports:

• What went wrong?
  The following error occurs when doing sls package when using an ErrorPath with States.Format()

SCHEMA_VALIDATION_FAILED: /States/Fail - My Fail State. must match exactly one schema in oneOf

• What did you expect should have happened?
  No error should have occurred
