Description

After upgrading to open-api generator version 6.2.0 and also present in 6.2.1 typescript angular code generator does not match path parameter when name is prefixed with '*', and therefore the parameter is not added to url request

openapi-generator version

6.2.0, 6.2.1
I presume this is a regression, since e.g. Java Spring generator still supports it

OpenAPI declaration file content or url

openapi: 3.0.0
info:
  version: 1.0.0
  title: Sample
paths:
  /file/fileContent/{*filePathName}:
    get:
      tags:
        - file
      summary: Returns the content of a file
      parameters:
        - name: filePathName      
          in: path
          required: true
          description: path to file with file name
          schema:
            type: string
      responses:
        '200':
          description: Successful Operation
          content:
            '*': #The server should return whatever the mimetype of the file is.
              schema:
                type: string
                format: binary

Generation Details

let localVarPath = `/file/fileContent/`;
return this.httpClient.request('get', `${this.configuration.basePath}${localVarPath}`, // <-- missing `filePathName`
  {
    context: localVarHttpContext,
    responseType: "blob",
    withCredentials: this.configuration.withCredentials,
    headers: localVarHeaders,
    observe: observe,
    reportProgress: reportProgress
  }
);

Steps to reproduce

using npm openapi-generator-cli generate
no specific config in openapitools.json

"additionalProperties": {
          "ngVersion": "12",
          "supportsES6": "true",
          "npmVersion": "6.9.0",
          "fileNaming": "kebab-case",
          "modelFileSuffix": ".model",
          "stringEnums": true,
          "taggedUnions": true
}

Suggest a fix

I think the issue is here in AbstractTypeScriptClientCodegen.findPathParameterByName

i suppose somewhere here it is handles in Java AbstractJavaCodegen.toParamName

Start in modules/openapi-generator/src/main/java/org/openapitools/codegen/languages/AbstractTypeScriptClientCodegen.java at findPathParameterByName, using the supplied OpenAPI path with the {*} parameter to reproduce the missing URL parameter. Compare its handling with AbstractJavaCodegen.toParamName and verify generated TypeScript Angular output includes filePathName in the request path.
