Hi our app facing this crashes 4 times for last one month,

from firebase crashlytics logs I concluded that this crash happens on registration step. from other posts I got that this error happening due to nil arguments but our app is build on ionic and Cordova not on swift so I don't know how this happening to us.

Please help me to fix this crash event.

Consider the Last Exception Backtrace section:

Last Exception Backtrace:
0 CoreFoundation  … __exceptionPreprocess + 216 (NSException.m:199)

Looking at the code for frame 2, it throws this exception when it’s been called with nil as the replacement string. I’ve no idea what frame 3 would be doing that. Looking further up the backtrace there’s a world of UIKit and WebKit code, which isn’t really my area of expertise. However, I’ve retagged your thread accordingly.
