Unable to get Bundle ID from certificate - Push iOS / Firebase

[CampaignerForLife]

Hello,

I'm trying to send push notifications, but in the iOS ones I get this message 

I've implemented iOS using Firebase. Could someone shed some light on this? Where could be the problem, the best steps to do the implementation of iOS using firebase (To check if something is wrong...) 

Thank you in advance!
