When using `fetch` for `client` or `httpClient`, the Fetch response type includes HTTP status for easier processing by the application.
To return a defined return type instead of an automatically generated return type, set this value to `false`.

#### explode

Type: `Boolean`.
Default: `true`

By default, the Fetch client follows the OpenAPI specification for query parameter explode behavior. This means that query parameters will be exploded unless explicitly set to `false` in the OpenAPI schema.

To maintain backward compatibility with the previous behavior (where only parameters with `explode: true` are exploded), set this value to `false`.

##### forceSuccessResponse

Type: `Boolean`.
