Hello, I'm in project to send message from ESP32 to my flutter app with GSM Client and Firebase Cloud Messaging. The board I'm using is ESP32 LilyGo SIM7000G

I've tried using Wifi client and it works fine, but when I changed the client with GSM client I'm having an error.
I'm having a Guru Meditation problem when initializing firebase setGsmClient with service account/OAuth2.0 because I want to use GSM for Firebase Cloud Messaging.
Everthing works fine when I Patch/Get to Firestore with GSM with the same configuration, but it gives me error when I integrating it with FCM. Please help me cause I don't really understand about debugging a memory issues.

Thank you,
and here is my setup code:
