The error middleware throws unhandler error for first container config and last router

[ajoshi31]

Expected Behavior

The unhandler error captures should pass through the error middleware and should send the proper error message. All route should behave same using by passing error to error middleware

Current Behavior

For any first container config that is imported and its last router is giving this error:

Error: Cannot set headers after they are sent to the client
    at new NodeError (node:internal/errors:405:5)
    at ServerResponse.setHeader (node:_http_outgoing:648:11)
    at processTicksAndRejections (node:internal/process/task_queues:95:5)
    at runNextTicks (node:internal/process/task_queues:64:3)
    at processImmediate (node:internal/timers:447:9)

Possible Solution

NA

Steps to Reproduce (for bugs)

controller.ts

import { Request, Response, NextFunction } from 'express';
import { injectable } from 'inversify';
import { BaseController } from '@sn/server';
import { AppError } from '@sn/core';
import { logDecorator } from '@sn/shared';

@injectable()
export class GetMetaController extends BaseController {
  constructor() {
    super();
  }

  @logDecorator()
  public async executeImpl(
    request: Request,
    response: Response,
    next: NextFunction
  ): Promise<any> {
    try {
      throw new Error('Throw some error');
      // return this.ok<any>(response, { user: 1 });
    } catch (err: any) {
      return this.fail(response, new AppError.UnexpectedError(err), next);
    }
  }
}

route.ts

import { NextFunction, Request, Response } from 'express';
import { inject } from 'inversify';
import { controller, httpGet } from 'inversify-express-utils';
import { ApiPath } from 'swagger-express-ts';
import TYPES from '@ioc/constant/Types';
import { GetRefVersionController } from '../controller/GetRefVersionController';
import { GetMetaController } from '../controller/GetMetaController';

@ApiPath({
  name: 'RefVersions',
  path: '/refVersion'
})
@controller('/refVersion')
export abstract class RefVersionRouters {
  constructor(
    @inject(TYPES.GetRefVersionController)
    private readonly _getRefVersionController: GetRefVersionController,

    @inject(TYPES.GetMetaController)
    private readonly _getMeta: GetMetaController
  ) {}

  @httpGet('/version')
  public async getAllRefVersion(
    request: Request,
    response: Response,
    next: NextFunction
  ) {
    return this._getRefVersionController.execute(request, response, next);
  }

  @httpGet('/meta')
  public async getMeta(
    request: Request,
    response: Response,
    next: NextFunction
  ) {
    return this._getMeta.execute(request, response, next);
  }
}

module_config.ts

import { AsyncContainerModule, interfaces } from 'inversify';

import { errorHandler } from '@core/error/ErrorHandler';
import TYPES from '@ioc/constant/Types';

import { RefVersionRouters } from './infrastructure/routers/RefVersionRouter';

import { GetRefVersionController } from './infrastructure/controller/GetRefVersionController';
import { GetMetaController } from './infrastructure/controller/GetMetaController';

const SystemConfigContainer = new AsyncContainerModule(
  async (bind: interfaces.Bind) => {
    try {
      RefVersionRouters;

      bind<GetRefVersionController>(TYPES.GetRefVersionController)
        .to(GetRefVersionController)
        .inRequestScope();
      bind<GetMetaController>(TYPES.GetMetaController)
        .to(GetMetaController)
        .inRequestScope();
    } catch (err: unknown) {
      errorHandler.handleError('SystemIOC Error', err as Error);
    }
  }
);

export { SystemConfigContainer };

Ioc_config.ts

import { Container } from 'inversify';

import { errorHandler } from '@core/error/ErrorHandler';
import TYPES from './constant/Types';
import { SystemConfigContainer } from '@system-module/SystemIocConfig';
import { CheckConfigContainer } from '../module/check/CheckConfig';
import { UserConfigContainer } from '@user-module/UserIocConfig';

const InversifyConfigContainer = async () => {
  const container = new Container();

  try {
    container.loadAsync(SystemConfigContainer);
    container.loadAsync(UserConfigContainer);
    container.loadAsync(CheckConfigContainer);
  } catch (err: unknown) {
    errorHandler.handleError('IOC Error', err as Error);
  }

  return container;
};

export { InversifyConfigContainer };

AppServer.ts

import 'reflect-metadata';
/* eslint-disable  @typescript-eslint/no-explicit-any */
// eslint-disable-next-line @typescript-eslint/no-var-requires
require('source-map-support').install();
import * as dotenv from 'dotenv';
import { InversifyExpressServer } from 'inversify-express-utils';
import { ExpressMiddleware, errorMiddleware } from './../middleware';
import { logger } from '@sn/shared';
// import { envConfig } from './config';
// import { ExitProcess } from './core/utils/ExitProcess';

dotenv.config();
const port = process.env.PORT || 3000;

export const appServer = async (config: any): Promise<void> => {
  try {
    const server = new InversifyExpressServer(config, null, {
      rootPath: '/api/v1'
    });

    /* Adding middleware to express server */
    server.setConfig((app) => {
      new ExpressMiddleware(app);
    });

    server.setErrorConfig(errorMiddleware);
    const serverInstance = server.build();

    serverInstance.listen(port, () => {
      logger.info(`Server running at http://127.0.0.1:${port}/`);
    });

    // ExitProcess(server);
  } catch (err) {
    logger.error('Error in SERVER', err);
  }
};

MainAppServer.ts:

import 'module-alias/register';
import 'reflect-metadata';
import { InversifyConfigContainer } from '@ioc/IocConfig';

import sourceMapSupport from 'source-map-support';
import { logger } from '@sn/shared';
import { appServer } from '@sn/server';

sourceMapSupport.install();

const expressApp = (async (): Promise<void> => {
  /* Setting up IoC */
  try {
    const containerConfig = await InversifyConfigContainer();
    await appServer(containerConfig);
  } catch (err) {
    logger.error('Error', err);
  }
})();

expressApp;

Context

If import is like this:

import { SystemConfigContainer } from '@system-module/SystemIocConfig';
import { CheckConfigContainer } from '../module/check/CheckConfig';
import { UserConfigContainer } from '@user-module/UserIocConfig';

Here the last route of import { SystemConfigContainer } from '@system-module/SystemIocConfig'; throws the error of request already sent

If we change the import like this

import { CheckConfigContainer } from '../module/check/CheckConfig';
import { SystemConfigContainer } from '@system-module/SystemIocConfig';
import { UserConfigContainer } from '@user-module/UserIocConfig';

Then last route of import { CheckConfigContainer } from '../module/check/CheckConfig'; throws the errror:

All other route works perfectly

Your Environment

• "inversify": "^6.0.1",
• "inversify-express-utils": "^6.4.3",

• nodejs : 18+

Hey @rsaz, is this related to inversify/inversify-express-utils#255?
