Command line used for generation

java -jar swagger-codegen-cli.jar generate
-i swagger.json
-l python
-o /out/ &>/out/pysdk-codegen.log

Reproduce the report with the shown Go structs and swagger.json using swagger-codegen 2.2.3 and the Python generator. Inspect the generated v1_interface_bridge.py output alongside the empty v1.InterfaceBridge definition in the generated JSON. Done means the empty model is generated while its reference remains usable in the Python client.
