[typescript-angular] Bug - Parameters named "localVarHeaders" cause conflict.

I get the following error when building my Angular v11 project:

Not a great forever solution, but short term openapi-generator-cli version-manager set 5.1.0 works

I think you can also workaround the issue by using customized templates (e.g. -t in the CLI option). Please refer to the project’s readme on how to do that.
