Description

I'm trying to generate the SDK with this endpoint definition:

  '/entities/{id}/secondentities':
    get:
      operationId: getSecondEntitiesByEntities
      tags:
        - channels
      parameters:
        - in: path
          name: id
          schema:
            type: integer
          required: true
        - $ref: '#/components/parameters/problematicParameter'
      responses:
        '200':
          $ref: '#/components/responses/data200'
        '404':
          description: Not found
        '500':
          description: Internal server error

and the parameter is described as a content/application-json complex object that should be serialized in the query string:

    problematicParameter:
      in: query
      required: false
      name: filter
      content:
        application/json:
          schema:
            $ref: '#/components/schemas/problematicParameterSchema'

The schema is something like this:

    problematicParameterSchema:
      type: object
      properties:
        tags:
          type: array
          items:
            type: string
        attributes:
          type: array
          items:
            type: string

The generated typescript code has a signature like this:

    public getSecondEntitiesByEntities(id: number, filter?: ProblematicParameterSchema, observe?: 'body', reportProgress?: boolean, options?: {httpHeaderAccept?: 'application/json'}): Observable<Array<PlacemarkData>>;

The model of ProblematicParameter is correctly generated, but when I call this function with a valid object of type ProblematicParameterSchema the URL is not generated correctly.

For example with:

getSecondEntitiesByEntities(1, {attributes: ['c', 'd'], tags: ['a', 'b']})

the generated URL is:

API_BASE/entities/{id}/secondentities?attributes="c"&attributes="d"&tags="a"&tags="b"

completely ignoring the name filter of the parameter.
The expected result should be something like this:

API_BASE/entities/{id}/secondentities?filter='{"attributes": ["c", "d"], "tags": ["a", "b"]}'

Suggest a fix

Start by running the shown OpenAPI Generator command with the reproduction specification and inspect the generated TypeScript client request for the application/json query parameter. Compare the serialized URL with the expected filter parameter, and consider the issue done when the generated client preserves the parameter name and serializes the object as described.
