After upgrade from Typescript 4.9 to 5 I get the following error:

      Argument of type 'undefined' is not assignable to parameter of type 'string | symbol'.

InjectModel uses Inject under the hood so as long as you update to the latest version of @nestjs/common you should be fine:

export const InjectModel = (model: string, connectionName?: string) => Inject(getModelToken(model, connectionName));
