ZoneMinder Forums

Hi asker and everyone,

My system is Zoneminder 1.32.3, ES version 6.1.27, zmNinja 1.6.009. Everything works perfectly with the current FCMV1 link 'https://us-central1-ninja-1105.cloudfun ... /send_push'. 

This is the debug log I got when using the current FCMV1 link:
FORK:Floor1 (4), eid:298774 fcmv1: Final JSON using FCMV1 being sent is: {"token":"fBJFbUdSToaEUVlRUvddlw:APA91bEWItPBz67gDP1Ra7pb2578zGt5tvVf1KwotcZ0jEmCzH4f_flq3_HUVCnvQ3S0LqfxYakxRIsVzOjX4JgsyvdM6DCQwO8E6mao1BbvDCkl9Jh_eEA6sVDM3ZXPBrREoI1fvMRF","android":{"priority":"high","channel":"zmninja","icon":"ic_stat_notification"},"title":"Floor1 Alarm (298774)","data":{"notification_foreground":"true","eid":"298774","mid":"4"},"image_url":"https://localhost/zm/index.php?view=ima ... ssword=xxx} to token: ...1fvMRF
DBG-1:2021-08-29,19:11:14 |----> FORK:Floor1 (4), eid:298774 fcmv1: FCM push message returned a 200 with body {"Success":"projects/ninja-1105/messages/0:1630239073797130%311426be311426be"}

I followed the instructions to set up Google cloud function (https://medium.com/zmninja/using-your-o ... 8897d0ff49). I kept the code intact and changed only the fcm_v1_url to my new 'Trusted App' via URL 'https://us-central1-zmninjatest.cloudfu ... send_pusha' and I could get new notifications on my Android phone. However I got this in the log "Invalid credentials: Signature verification failed" although I keep intact “<YOUR_SECRET_HERE>” and DEFAULT_FCM_V1_KEY in zmeventnotification.pl and zmeventnotification.ini. If I restart my PC then I could not receive notifications on my phone anymore. If I use the FCMV1 link 'https://us-central1-ninja-1105.cloudfun ... /send_push', everything works normal again.

I tried to set up OAuth consent screen for my 'Trust App' in APIs & Services in my Google Cloud Platform and used a new token in fcm_v1_key but I still get "Invalid credentials" in the debug log although I still get notifications on my phone.

Could you please help me to resolve this problem? Many thanks in advance.

Hieu

Here is the debug log I got when I use my new Google cloud function URL. I still receive notifications on my Android phone if I do not restart the PC.

When you are setting up your own function, you need to both change the URL and the secret

I've changed the article to add more details. Hope that helps

Many thanks for your help! I will follow the new instructions in your article.

Hi asker,
Could you please help me again? I have successfully deployed my own function but I got the error “SenderId mismatch” both in ES log and in Firebase log

Firebase log
token:OiX0smzkvv=>SenderId mismatch

I found this possible answer for the error “SenderId mismatch” which I quote here:
https://stackoverflow.com/questions/378 ... es#tab-top
“Main issue was in device_ID(UDID) to whom I have to send the notification. Actually DeviceId we got on android side in FCM is different than GCM. You can't use GCM created DeviceId in FCM. I had to ask for the app developer to include the sender id on the code, then my FCM API KEY worked.”
Could you please help me to resolve this “SenderId mismatch” error?
Many thanks for your help!

Hmm,
So reading https://stackoverflow.com/questions/491 ... rebase-api

I think this is the situation:

a) zmNinja is configured to receive message only from a specific project (see this). So when it starts up, it gets a tokenID that can receive messages from the firebase project it is associated with
b) Your cloud function doesn't belong to that project

So maybe you just setting up a new cloud function is not the full story. You may need to re-compile zmNinja to use your google-services.json


This is a guess to be honest, needs experimentation

Thank you. I will try to re-compile zmNinja for further testings.

Is it confirmed that a user needs to compile zmNinja themself with their GCP project URL hardcoded somewhere?

Sorry, I haven't recompiled zmNinja yet. I hope someone in this forum may try to do this and let us know the results.
