openapi.txt

This is the file having API spec in YAML format causing the above issue

try removing the - on the type field and repositioning the allOf reference. allOf needs a property association

should look like this:

    FormFieldComponent:
      type: object
      properties:
        components:
          allOf:
            - $ref: '#/components/schemas/DataComponent'
            - $ref: '#/components/schemas/Component'
        label:
          type: string
        hint:
          type: string
        placeholder:
          type: string
        apply:
          $ref: '#/components/schemas/Apply'

@jeremyfiel We generated this YAML using micronaut-openapi(io.micronaut.openapi:micronaut-openapi:3.2.0).

Does that mean it is generated file in wrong format ?

And we don't have a property named "components" in FormFieldComponent

• DataComponent extends Component
• FormFieldComponent extends DataComponent

Hence the file is generated is like this

@prabhutw I may have misunderstood it previously.

I think it may be associated to this https://github.com/Redocly/redoc/issues/907

sounds like it may not be able to discriminate between object <> string in your oneOf declaration

Thanks for pointing it out @jeremyfiel But converting the error to warning did not solve the issue. What could be fix for this issue? I can contribute for this

Just ran into the same issue. Causes Chrome to crash. Not a complicated schema
