[REQ] Print line number when there is an error in the swagger doc

Is your feature request related to a problem? Please describe.

Please print line numbers when there is an error

Describe the solution you'd like

I am trying to generate nestjs from swagger, using this command:

openapi-generator-cli generate -i clean_oapi.json -g typescript-nestjs -o ../gen/

and I get an error like this:

-attribute paths.For path parameter id the required value should be true

I would like to know the line number of the swagger where the error is located, so i can fix it.

Describe alternatives you've considered

the best way is to have the line number

Additional context

The reported entry point is openapi-generator-cli generate with clean_oapi.json and the typescript-nestjs generator; start by tracing where the OpenAPI validation error for paths path parameters is produced. Done means the same error identifies the source line in the Swagger document, with coverage for this validation path.
