Description

Hello, I use API Platform as API server and I use OpenAPI Generator to generate client for it from OpenAPI 3 Specs. API-Platform uses : as logical divider in Schema names and OpenAPI Generator does not like it.

-attribute components.schemas.Schema name CategoryProductTypeResource:jsonld doesn't adhere to regular expression ^[a-zA-Z0-9.-_]+$

openapi-generator version

3.1.0

OpenAPI declaration file content or url

https://pastebin.com/NHKAFep8

Command line used for generation

openapi-generator generate -i openapi.json -g javascript -o client --additional-properties usePromises=true,useES6=true

Steps to reproduce

1. Use provided OpenAPI declaration file content and command line for generation.

Suggest a fix

I'm not sure whether the problem is in Api-Platform, or the requirements of OpenAPITools are too strict.

Maybe add option to provide some kind of rename mapping:
{
"Category:jsonld-category_logo": "CategoryCategoryLogo"
}

Reproduce the report with the linked OpenAPI declaration and the shown JavaScript generation command, then trace where schema names are validated. Determine whether the generator or the input specification should change, and document the expected handling of names containing colons, including any rename mapping behavior.
