throw _iteratorError

[funkenstrahlen]

I am running version 1.2.0 of parse-server-push-adapter. I added osx push config to my server configuration. Now the app crashes on startup with throw _iteratorError.

This is how my push config does look like:

  push: {
    ios: {
      pfx: __dirname + '/certs/' + process.env.APNS_IOS_CERTIFICATE, // The filename of private key and certificate in PFX or PKCS12 format from disk  
      bundleId: process.env.BUNDLE_ID_IOS, // The bundle identifier associate with your app
      production: is_production // Specifies which environment to connect to: Production (if true) or Sandbox
    },
    osx: {
      pfx: __dirname + '/certs/' + process.env.APNS_OSX_CERTIFICATE, // The filename of private key and certificate in PFX or PKCS12 format from disk  
      bundleId: process.env.BUNDLE_ID_OSX, // The bundle identifier associate with your app
      production: is_production // Specifies which environment to connect to: Production (if true) or Sandbox
    }
  },

All configuration variables are set.

Expected:

parse server push adapter should throw an error that osx is unsupported push type as this is only supported with release 1.3.0.

Actual result:

It crashes with throw _iteratorError;.

thoughts:

I think _iteratorError in this case is actually the correct error I expect (throw new Parse.Error(Parse.Error.PUSH_MISCONFIGURED, 'Push to ' + pushType + ' is not supported');. However parse server does not print the error correctly to the user as you can see here: https://github.com/ParsePlatform/parse-server/blob/c1dcaf12712eb025d502387e564d3b9c1093a768/src/Adapters/AdapterLoader.js

Therefore I never see the actual error message. Maybe this is an error of parse-server in this case.

Yeah not really, that would imply releasing a 1.2.1 with that ;)

[funkenstrahlen]

      if (this.validPushTypes.indexOf(pushType) < 0) {
        throw new Parse.Error(Parse.Error.PUSH_MISCONFIGURED,
                              'Push to ' + pushType + ' is not supported');
      }

This is already present in 1.2.0.

[flovilmart]

Shouldn't the push config be:

push: {
    ios:[{
      pfx: __dirname + '/certs/' + process.env.APNS_IOS_CERTIFICATE, // The filename of private key and certificate in PFX or PKCS12 format from disk  
      bundleId: process.env.BUNDLE_ID_IOS, // The bundle identifier associate with your app
      production: is_production // Specifies which environment to connect to: Production (if true) or Sandbox
    }],
    osx: [{
      pfx: __dirname + '/certs/' + process.env.APNS_OSX_CERTIFICATE, // The filename of private key and certificate in PFX or PKCS12 format from disk  
      bundleId: process.env.BUNDLE_ID_OSX, // The bundle identifier associate with your app
      production: is_production // Specifies which environment to connect to: Production (if true) or Sandbox
    }]
  },

[funkenstrahlen]

It does support array or no array:

  let apnsArgsList = [];
  if (Array.isArray(args)) {
    apnsArgsList = apnsArgsList.concat(args);
  } else if (typeof args === 'object') {
    apnsArgsList.push(args);
  } else {
    throw new Parse.Error(Parse.Error.PUSH_MISCONFIGURED,
                          'APNS Configuration is invalid');
  }

So leaving the array away as I only have one certificate per deviceType is valid. It makes no difference to the error message if I add the arrays to the push config (just tried that).

[flovilmart]

uhh that's odd...

[funkenstrahlen]

I think _iteratorError is created by this code:

    try {
      for (var _iterator = pushTypes[Symbol.iterator](), _step; !(_iteratorNormalCompletion = (_step = _iterator.next()).done); _iteratorNormalCompletion = true) {
        var pushType = _step.value;

        if (this.validPushTypes.indexOf(pushType) < 0) {
          throw new _parse2.default.Error(_parse2.default.Error.PUSH_MISCONFIGURED, 'Push to ' + pushTypes + ' is not supported');
        }
        switch (pushType) {
          case 'ios':
          case 'tvos':
          case 'osx':
            this.senderMap[pushType] = new _APNS2.default(pushConfig[pushType]);
            break;
          case 'android':
          case 'fcm':
            this.senderMap[pushType] = new _GCM2.default(pushConfig[pushType]);
            break;
        }
      }
    } catch (err) {
      _didIteratorError = true;
      _iteratorError = err;
    } finally {
      try {
        if (!_iteratorNormalCompletion && _iterator.return) {
          _iterator.return();
        }
      } finally {
        if (_didIteratorError) {
          throw _iteratorError;
        }
      }
    }
  }

This is in lib/ParsePushAdapter.js.

I know there will be no problem with osx after 1.3.0 release. However this is an issue affecting all misconfigured push configurations.

[MamdouhSar]

I am facing the same problem with ios push notification,

push: {
    ios:
      [{
        pfx: __dirname  + process.env.CERT_PATH, // Dev PFX or P12
        bundleId: process.env.BUNDLE_ID,
        passphrase: process.env.CERT_PASSPHRASE,
        production: true
      }]
 }

Here's the error

parse-server-push-adapter/lib/ParsePushAdapter.js:81
          throw _iteratorError;
          ^
[object Object]

[flovilmart]

Seems to be a problem with the babel bump

[funkenstrahlen]

If I remove the osx push configuration and use it like @MamdouhSar I do not see this error!

  push: {
    ios: {
      pfx: __dirname + '/certs/' + process.env.APNS_IOS_CERTIFICATE, // The filename of private key and certificate in PFX or PKCS12 format from disk  
      bundleId: process.env.BUNDLE_ID_IOS, // The bundle identifier associate with your app
      production: is_production // Specifies which environment to connect to: Production (if true) or Sandbox
    }
    // ,osx: {
    //   pfx: __dirname + '/certs/' + process.env.APNS_OSX_CERTIFICATE, // The filename of private key and certificate in PFX or PKCS12 format from disk  
    //   bundleId: process.env.BUNDLE_ID_OSX, // The bundle identifier associate with your app
    //   production: is_production // Specifies which environment to connect to: Production (if true) or Sandbox
    // }
  }

So maybe there is some other issue with the configuration of @MamdouhSar but the error message is not displayed correctly due to babel?

[flovilmart]

Perhaps an issue with babel, let's see if we can either fix it or remove babel altogether :)

[kelset]

Any update on this?

[flovilmart]

please update to the latest version of parse-server and open a new issue if needed.
