Logs/Trace

[jiawenzhang]

I have created GCM credentials and enabled Google Cloud Messaging in google cloud platform. I also added the push senderId and apiKey in Parse Server's index.js

var api = new ParseServer({
.
.
.
push: {
      android: {
          senderId: 'Project number',
          apiKey: 'XXXXXXXX'
      }
    }
});

when I test sending push using the following REST api call:

curl -X POST \
         -H "X-Parse-Application-Id: myAppId" \
         -H "X-Parse-Master-Key: foo" \
         -H "Content-Type: application/json" \
         -d '{
             "where": {
                 "deviceType": {
                     "$in": [
                         "android"
                         ]
                 }
             },
                 "data": {
                 }
         }' \

I saw this log:

GCM request and response {"request":{"params":{"priority":"normal","data":{"time":"2016-02-27T22:19:17.914Z","push_id":"PASML5ShpI","data":"{\"friendRequestUpdate\":0}"}}},"response":{"multicast_id":5176387894691562000,"success":0,"failure":1,"canonical_ids":0,"results":[{"error":"MismatchSenderId"}]}}

why does it return MismatchSenderId error?

[gfosco]

Was this an installation migrated from parse.com? Is that the senderId which was used to register this device?

[jiawenzhang]

How will installation affect REST api call from command line? In my test, there are no installations migrated from parse.com. When I delete all the installations on mongodb and run the test push command, server logs shows the same error of MismatchSenderId.

It also logs Can not find sender for push type ios, {"where":{"deviceType":{"$in":["android"]}},"data":{}}
But I think it is unrelated as I didn't specify iOS push in index.js

[jiawenzhang]

Odd! I tested again and now push is successfully received. Nothing has changed in my code. I suspect something fishy was going on in GCM

[jiawenzhang]

I found the problem, I put

 <meta-data android:name="com.parse.push.gcm_sender_id"
                android:value="id:xxxxxxxxx" />

outside the application section in the AndroidManifest. The app still compiles and runs but I guess the sender_id is not used from the client?

When I move it to inside application, push works.

@gfosco Thanks.
