A valid status code is required for the POST request in TSOA Typescript. Please ensure it is a numerical

While exploring the possibilities of using tsoa for designing a rest API, I encountered an issue with the post request that always leads to the following error message:

AssertionError [ERR_ASSERTION]: status code must be a number
      at Object.set status [as status] (PROJECT_PATH/node_modules/koa/lib/response.js:87:5)
      at Object.status (PROJECT_PATH/node_modules/delegates/index.js:92:31)
      at Object.<anonymous> (PROJECT_PATH/src/rest/routes.ts:93:31)
      at Generator.next (<anonymous>)
      at PROJECT_PATH/src/rest/routes.ts:8:71
      at new Promise (<anonymous>)
      at __awaiter (PROJECT_PATH/src/rest/routes.ts:4:12)
      at RegisterRoutes.router.post (PROJECT_PATH/src/rest/routes.ts:84:43)
      at dispatch (PROJECT_PATH/node_modules/koa-compose/index.js:42:32)
      at PROJECT_PATH/node_modules/koa-router/lib/router.js:353:16

The sample code segment causing this issue is as follows:

  @Post()
  public async createUser(@BodyProp() requestBody: UserInput): Promise<void> {
    console.log(requestBody)
    // code
    this.setStatus(201);
    return Promise.resolve();
  }

In my configuration within the tsoa.json file, I included "middleware": "koa", since I am utilizing kao.

Answer №1

Encountering a similar error, I found a solution by incorporating the koa-bodyparser middleware. This middleware ensures that the http body is appended to the koa ctx.request object.

The documentation for tsoa did not mention this fix.

Here is an example of how to implement it:

    @Post('')
    public async handleRequest (
        @Request() req: Request,
        @BodyProp('param_1') param1: number
    ): Promise<void> {
        // These will all output the http body
        console.log(param1)
        console.log(req.body)
        console.log(req.ctx.request.body)
    }
