Awilix is not creating instance of the class i pass as an dependency

[jeffijoe]

It looks like you are mixing injection modes, but its hard to tell without your container configuration

[kiratxsinghx]

thanks for your reply

here are my container configuration

const container = awilix.createContainer();

class Container {
    constructor(keys) {
        container.register({
            config: `awilix.asClass(config).setInjectionMode(awilix.InjectionMode.CLASSIC).singleton(),`
            authenticationService : awilix.asClass(AuthenticationService),
            authenticationController : awilix.asClass(AuthenticationController),
            DateUtil : awilix.asValue(DateUtil),
            RestUtil : awilix.asClass(RestUtil),
            CommonUtil : awilix.asValue(CommonUtil),
            MailUtil : awilix.asValue(MailUtil),
            MessageUtil : awilix.asValue(MessageUtil),
            OauthUtil : awilix.asClass(OauthUtil),
        }),
        this.resolve = this.resolve.bind(this);
    }
    resolve(key) {
        return container.resolve(key);
    }
}

module.exports = Container;

[jeffijoe]

Yes, as I suspected, you are mixing injection modes which I don’t recommend. One of your modules are likely treating a parameter as some other module but in reality its the container cradle (proxy).

[kiratxsinghx]

so now did some changes in code

const container = awilix.createContainer();
class Container {
    constructor(keys) {
        container.register({
            config: awilix.asClass(config).singleton(),
            authenticationService: awilix.asClass(AuthenticationService),
            authenticationController: awilix.asClass(AuthenticationController),
            RestUtil: awilix.asClass(RestUtil),
            OauthUtil: awilix.asClass(OauthUtil),
            DateUtil: awilix.asValue(DateUtil),
            CommonUtil: awilix.asValue(CommonUtil),
            MailUtil: awilix.asValue(MailUtil),
            MessageUtil: awilix.asValue(MessageUtil),
        }),
            this.resolve = this.resolve.bind(this);
    }
    resolve(key) {
        return container.resolve(key);
  
``

[jeffijoe]

Either avoid mixing injection modes or find the module that is assuming CLASSIC but is actually using PROXY (default).

[kiratxsinghx]

so now i am only using proxy as an injection mode but it is giving me the same error

AwilixResolutionError: Could not resolve 'Symbol(Symbol.toPrimitive)'.

Resolution path: Symbol(Symbol.toPrimitive)
``

[jeffijoe]

What are you resolving first?

[kiratxsinghx]

i am resoling authenticationController in my authenticationRouter module

const Container = require("../container") ;
const ContainerINST = new Container() ;
const AUTHENTICATIONCONTROLLERINST = ContainerINST.resolve("authenticationController") ;``

[jeffijoe]

Then look at the constructor of AuthenticationController, you are likely treating it as CLASSIC even though it's registered as PROXY.

[kiratxsinghx]

here is the constructor of authentication controller

class AuthenticationController {
  constructor({authenticationService, config, DateUtil,RestUtil, CommonUtil, MessageUtil, OauthUtil}) {
    this.DateUtil = DateUtil ;
    this.config = config ;
    // console.log("config here:::::::::::", this.config)
    this.authService = authenticationService;
    // this.authService = new AUTHENTICATIONSERVICE(config);
    this.rbacController = new RBACCONTROLLER(this.config);
    this.restUtil = RestUtil;
    this.OauthUtil = OauthUtil;
    this.CommonUtil = CommonUtil;
    this.MessageUtil = MessageUtil ;

[jeffijoe]

What is the full stack trace of the error?

[kiratxsinghx]

so what im doing is im resolving the AuthentiationController from theAuthenticationRoute

const Container = require("../container") ;
const ContainerINST = new Container() ;
const AUTHENTICATIONCONTROLLERINST = ContainerINST.resolve("authenticationController") ;

then im calling FindUserByEmailForLogin function from the AuthentiationController
router.get("/login/:email",checkJwt, AUTHENTICATIONVALIDATIONINST.findUserByEmailForLogin(), result_validator, AUTHENTICATIONCONTROLLERINST.findUserByEmailForLogin);

and then in AuthentiationController constructor im destructing the dependcies

class AuthenticationController {
  constructor({authenticationService, config, DateUtil,RestUtil, CommonUtil, MessageUtil, OauthUtil}) {
    this.DateUtil = DateUtil ;
    this.config = config ;
    // console.log("config here:::::::::::", this.config)
    this.authService = authenticationService;
    // this.authService = new AUTHENTICATIONSERVICE(config);
    this.rbacController = new RBACCONTROLLER(this.config);
    this.restUtil = RestUtil;
    this.OauthUtil = OauthUtil;
    this.CommonUtil = CommonUtil;
    this.MessageUtil = MessageUtil ;

and In FindUserByEmailForLogin im calling a function from OauthUtil (i pass OauthUtil as dependency in AuthentiationController)

class OauthUtil {
    constructor({config, RestUtil, CommonUtil, MessageUtil}) {
        console.log("here in the oath Util")
        this.config = config;
        this.CommonUtil = CommonUtil;
        this.restUtil =  RestUtil;
        this.MessageUtil = MessageUtil;
        this.mongoose = new MONGOOSEDB();

and then In OauthUtil 's Function CreateAccessToken I am using RestUtil which i pass as an dependency in OauthUtil's constructor

  async createAccessToken(type, update_time) {
       try {
           let data = {
               "client_id": this.config.get('client_id'),
               "client_secret": this.config.get('client_secret'),
               "audience": `${this.config.get('audience_management_api')}`,
               "grant_type": "client_credentials"
           };
           let options = {
               headers: { 'content-type': 'application/json' },
           }
           let url = this.config.get('oauth:token_url');
           let response = await this.restUtil.postRequest(url, data, options);
           this.storeAccessToken(type, response.data, update_time, this.MessageUtil.info().oauth_token.management)
           return response.data;
       } catch (err) {
           console.log("err createAcceessToken:::", err)
           throw new Error(err);
       }
   }

when i restUtil Try to call its function PostRequest its is giving me an error

[jeffijoe]

If you look at the stack trace, it'll give you some hints. For example, Axios' dispatchHttpRequest is somehow triggering resolve in Awilix. This likely means you passed in the cradle somewhere to Axios, likely in your restUtil.

Looking at Axios's source code, there is exactly one parseInt in dispatchHttpRequest, which is parsing a timeout config. So my guess is your restUtil is passing in the cradle, which in turn makes parseInt attempt to convert the value to a primitive by x[Symbol.toPrimitive], which then triggers the resolve.

hi jeff thanks for your help my pervious error got resolved..
now what i m trying to do is register dependencies using loadModules

but loadModules is not working as it is not registering any dependencies

my code :

` .loadModules([
            "service/**/*",
            "controller/**/*",
            "routes/**/*",
        ],
            {
                resolverOptions: {
                    lifetime: awilix.Lifetime.SCOPED,
                    register: awilix.asClass,
                },
                formatName: 'camelCase'
            }
        )
        this.resolve = this.resolve.bind(this);
        console.log("In the container.js",container.registrations )
    }`

app structure::

-->app
         -->service
                       ->userService
                       ->anyotherservice
           -->controller
                       ->userController
                       ->anyotherController
          -->routes
                       ->userRoutes
                       ->anyotherRoutes
         -->Contanier.js

ERROR : AwilixResolutionError: Could not resolve 'authenticationRoute'.
any Suggestions or advice :)

[jeffijoe]

Have you followed the documentation for how to set up your modules for auto-loading?

[jeffijoe]

Closing this since it's not an issue.
