Why is "Generate Flows from REST API" option disabled in anypoint platform?

Question

I am trying to create a new API interface Mule configuration from an API RAML file. First - I published an API to Anypoint Exchange and then imported api from the design center to Anypoint Studio project. Now, when I am right-clicking the API RAML file and selecting Mule > Generate Flows from REST API, this option is coming as disabled and I cannot select it.

I am using Mule 4 and Anypoint Studio Version: 7.3.2. I verified the API RAML file and there are no visible errors in it. What is causing this option to be disabled and how can I enable it?

Below is the actual API RAML file.

#%RAML 1.0

  Account: !include datatypes/account.raml

If the option is not available that means that Studio is not able to parse the RAML.

Recently there was a change in Design Center on how it is dealing with the examples node in RAML.

Details here: https://docs.mulesoft.com/design-center/design-modify-raml-specs-conform

In this case the RAML in Design Center is valid but due to a bug in Studio this is not seen as valid in Studio at the moment.

Try using Named Examples in your RAML for the examples nodes.

examples:  
  myNamedExample: !include examples/accountsExample.raml
