Pascal case class name for request class

Description

I'm creating a custom Typescript template for Angular 7 app. I used existing template as starter. In the api.service.mustache I added:

{{#operations}}
	{{#operation}}
	export class {{nickname}}Request {
		{{#allParams}}{{^isConstEnumParam}}{{paramName}}{{^required}}?{{/required}}: {{{dataType}}}; {{/isConstEnumParam}}
	{{/allParams}}
	}
	{{/operation}}
{{/operations}}

which results to

export class someClassNameRequest {
/////
}

I can not come up with the solution to make it pascal case like SomeClassNameRequest. Now I use {{nickname}} as a prefix but opened to use any other variable with a descriptive name. I tried to figure out how to see the whole object that is sent to the mustache template without any success.

Any suggestions are welcome.

Command line used for generation

rm -rf ./src/app/core/web-api; mkdir ./src/app/core/web-api; npx swagger-codegen generate -i ./swagger/swagger.yaml -l typescript-angular -o ./src/app/core/web-api -t ./swagger-codegen-typescript-angular

Start with the custom api.service.mustache template and the typescript-angular template resources, then run the provided swagger-codegen command against the example declaration. Check how nickname and other operation fields are exposed to templates and verify that the generated request class uses the desired PascalCase name.
