Code of my stepfunctions , note thas sf_6 pass perfectly :

  # Before
  sf_6:

    role: arn:aws:iam::958531303673:role/service-role/StepFunctions-DMSCreateReplicationInstance-role-566d43b8
    definition:
      ${file(./sls_imports/step_functions/06_parallelize_buffers.asl.yaml)}
    tracingConfig:
      enabled: true
# New code  test ok with minus
