Generate API error "KeyError: 'schema_node_id'"

[AlbrechtL]

Thanks for this great tool!

Today I tried to generate an OpenAPI API with the "Generate API" function. Unfortunately this doesn't work (see screenshot below) and python is throwing the error KeyError: 'schema_node_id'. I'm using the one docker solution in the latest version.

It seems that the openconfig-vlan yang module is not supported (see picture below).
