When running the api-documenter on the api.json file of the @uifabric/utilities package I get this error thrown:

When looking at the eventgroup.yml file generated I indeed see that they are the same:

... upon further digging into the package itself I found that the issue is from the EventGroup class has 2 methods with the name of raise. The only difference is that one is public static and the other one is just public.

Is this something that is a @uifabric/utilities package issue that needs to be addressed or api-documenter needs somehow to take that into the account?

For reference, this is what the api.json file has for both methods:

... and the error is most likely is thrown by this line in the typescript.schema.json:
