iOS 14 Only attempt to insert nil object from objects[0]

[sergey-g-s]

Hi all. This is a problem that I only got on devices with iOS 14.

Description

My project worked well on iOS 13 and after I tried to run it on iOS 14 I always get an error in xcode

Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[__NSPlaceholderDictionary initWithObjects:forKeys:count:]: attempt to insert nil object from objects[0]'

Hi @Sergey-grishko, based on your logs it seems like it is a Firebase issue. I would recommend opening an issue with the firebase module. Feel free to create a new issue if this occurs in a raw React Native template.
