[piraveena]

I'm trying with gnostic-grpc to convert a yaml file to proto file. I tried with my own sample obtained the above error. So i tried with the bookstore.yaml file.

Plugin error: [cycle in imports: swagger.proto -> swagger.proto]%    

Go version: go version go1.19 darwin/amd64
And I'm using latest gnostic-grpc

Any idea why I'm getting above errors

I've also got these errors. Could someone take a look?

Hey, I encountered the same issue.

The easiest way to fix it is specifying a relative path to OpenAPI contract instead an abosule path.

Other possible solution:
The issue is most probably on gnostic side. Particularly, function isSymbolicReference works wrong if an absolute path specified.

One can try to add condition "if sourceName and ref are not the same file" in the if-statement.
It will break support of OpenAPI contracts distributed among multiple files. For example, other.yaml test will fail
