Using the same the petstore swagger.json, the generated TypeScript includes the following code:

		loginUser(__params: UserApi.LoginUserRequest, options?: RequestInit): (fetch?: FetchAPI, basePath?: string) => Promise<UserApi.LoginUserResponse> {
			const localVarFetchArgs = UserApiFetchParamCreator(configuration).loginUser(__params, options);
			return async (fetch: FetchAPI = defaultFetch, basePath: string = BASE_PATH) => {
				const response = await fetch(basePath + localVarFetchArgs.url, localVarFetchArgs.options)
				const contentType = response.headers.get('Content-Type');
				const mimeType = contentType ? contentType.replace(/;.*/, '') : undefined;
				
				if (response.status === 200) {
					if (mimeType === 'application/json') {
						return {
							status: 200,
							contentType: 'application/json',
							body: await response.json() as string,
							headers: {
								xExpiresAfter: response.headers.get('X-Expires-After'),
								xRateLimit: response.headers.get('X-Rate-Limit'),
							},
						}
					}
					if (mimeType === 'application/xml') {
						return {
							status: 200,
							contentType: 'application/xml',
							body: await response.text(),
							headers: {
								xExpiresAfter: response.headers.get('X-Expires-After'),
								xRateLimit: response.headers.get('X-Rate-Limit'),
							},
						}
					}
					throw response;
				}
				if (response.status === 400) {
					return {
						status: 400,
						/* No content */
					}
				}
				throw response;
			};
		},

It doesn't compile because of the following error,

@taras thank you for reporting this... could you please post what was generated for UserApi.LoginUserResponse?

@karlvr thank you for looking into it. I pushed the generated code to a repo. You can find it here https://github.com/taras/backstage-openapi-client-scaffolding/blob/main/plugins/petstore-client-common/src/__generated__/api.ts#L1691
