Description

Normalizer outputs the following line when an OpenAPI 3.1.0 API definition was given.
The below {} should be type information.

[main] ERROR o.o.codegen.OpenAPINormalizer - Type {} not yet supported in openapi-normalizer to process OpenAPI 3.1 spec with multiple types.

The above should be like the following saying the type is 'object'.

[main] ERROR o.o.codegen.OpenAPINormalizer - Type object not yet supported in op
enapi-normalizer to process OpenAPI 3.1 spec with multiple types.

The above message is output at below.

openapi-generator version

I noticed this when I'm using 7.10.0, but and the latest master (7.20.0-SNAPSHOT but almost the same as 7.19.0)
also has the same issue.

OpenAPI declaration file content or url

I'm processing an automotive standard written in OpenAPI 3.1.0 available at:
https://standards.iso.org/iso/17978/
But, the above has 2 issues regarding validation.

Generation Details

Steps to reproduce

Reproducing procedure is complex, because the spec also has issues.
We need to modify at least 2 lines of the OpenAPI definition to reproduce
But as it's an obvious bug, a kind of very low hanging fruit, IMHO

java -jar PATH_TO/openapi-generator-cli.jar generate -g spring -o OUTPUT_DIR ./sovd-api.yaml

Related issues/PRs

Suggest a fix

Append String.valueOf(type) like below.
