[Bug]: OpenAPI Conversion With Missing OperationIds Error Message

[adstep]

Describe the bug

I was trying to generate a csharp client library for Partner Center OpenApi v3 using typespec for the first time. I hit an error trying to translate the OpenApi spec to typespec.

Seems like it might be related to the fact that the OpenApi spec doesn't define operationIds. Took me a while to figure this out as the error isn't very clear what's going on. If it is the case, might want to add some better error handling to call out that as a requirement.

Reproduction

tsp-openapi3 .\swagger.json --output-dir ./tsp-output
TypeError: Cannot read properties of undefined (reading 'split')
