Description
Trying to process the OpenAPI spec from the Owlery system, https://github.com/phenoscape/owlery (spec posted below) with the python and python-experimental systems, I get errors processing the files.
Using the command-line locally I get:
Exception in thread "main" java.lang.RuntimeException: Could not process operation:
Tag: class Tag {
name: Knowledgebases
description: null
externalDocs: null
}
Operation: null
Resource: get /kbs
Schemas: {}
Exception: Cannot read field "isEnum" because "cp" is null
Using the docker image I get:
Exception in thread "main" java.lang.RuntimeException: Could not process operation:
Tag: class Tag {
name: Knowledgebases
description: null
externalDocs: null
}
Operation: null
Resource: get /kbs
Schemas: {}
Exception: null
