FileLogger.sendLogFilesByEmail() crashes app on iOS

[tysoc1222]

Hello,

Currently when FileLogger.sendLogFilesByEmail() is called on iOS, it crashes the app.

I have confirmed this crash happens in the following two scenarios

Device: Simulator iPhone 16 pro
iOS version 18.4
react-native version: 0.76.9
new architecture enabled
react-native-file-logger version 0.6.0

Device: iPhone 16 device
iOS version: 18.5
react-native version: 0.76.9
new architecture enabled
react-native-file-logger version 0.5.6

XCode exception:
Exception NSException * "*** -[__NSPlaceholderDictionary initWithObjects:forKeys:count:]: attempt to insert nil object from objects[0]" 0x0000600000d02100

UDPATE 1hr later: I tried to create a minimal reproduction using a fresh app created with react-native-cli on RN version 0.76.9, but the simulator does not crash

Hello,
Can you show me the call to sendLogFilesByEmail on the JS side?
It might be due to a null value being passed in the function parameters 🤷‍♂️

This was it! I was calling FileLogger.sendLogFilesByEmail() without any arguments. Through some trial and error I found that as long as I set both subject and body fields, then it works as intended!

To summarize:

Calling as below causes the app to crash

FileLogger.sendLogFilesByEmail();

Calling as below works!

FileLogger.sendLogFilesByEmail({ body: '', subject: '' });

Hmm, that's strange. I tried to reproduce the bug on the sample app, but everything works fine on my end.

No worries—what matters is that you managed to solve the issue.
