const onError = (error: Error) => {
  appLogger.error(error.message, error.stack, 'Config');
  process.exit(1);
};
 
export const ConfigModule = DynamicConfigModule.forRoot({
  logger: appLogger,
  source: DynamicConfigSource.FILE,
  configFilePath: process.env['CONFIG_FILE'], // 
  watchForChanges: !isTestEnv(), // Chokidar causes Jest to leak memory in tests.
