Openapi Generator Fails on allOf

[kksteini]

What?

When updating to the latest driving-license-book client we get curious messages when running the external-openapi-generator.
The generation does not succeed fully and a lot of types/models are replaced by unknownBaseType which then results in our code not compiling due to typescript errors.

To reproduce

Have XROAD proxy running.

• yarn nx run clients-driving-license-book:update-openapi-document
• yarn nx run clients-driving-license-book:schemas/external-openapi-generator

The clientConfig.json generated in the first step is a valid openapi format when passed through a validator.

Possibly related issues

I've found these issues:

• [BUG][JAVA] Bug generating spring server: codegenModel is null. Default to UNKNOWN_BASE_TYPE OpenAPITools/openapi-generator#2236
• [BUG] [JAVA] UNKNOWN BASE TYPE when using allOf in request body schema declaration OpenAPITools/openapi-generator#2892
  They closely mimic the symptoms of this current issue. Curiously I do not find much on this issue for the javascript client.

Solutions

• In a recent PR, feat(clients-driving-license-book): Student overview update #11857, I had to manually edit the allOf blocks in the clientConfig since every one of them only had a single reference entry and they could be omitted. Not a great solution but possible in very certain situations. Advantages: not costly in terms of work. Disadvantages are that this doesn't fix anything, really.

• Update the openapi generator. Haven't looked deeply into this, but if we go from a major version of 1 to 2, then things start breaking pretty quickly. I tried these following versions as an update but they still had the errors present: [1.0.18-5.0.0-beta2 and 1.0.18-4.3.1]

This issue is stale because it has been open for 5 days with no activity. Remove stale label or this will be closed in 1 day.

This issue's been twiddling its thumbs for 5 days. Daydreaming, perhaps? Best do something or it's curtains in 1 day. Nudge off the stale label to give it another go.

This issue's shut up shop. Gave it a day post-stale, then decided, "Enough's enough!"
