It seems there's a bug in this place:

https://github.com/apache/cordova-plugin-camera/blob/master/src/ios/CDVCamera.m#L591

Here self.data is nil then PNG option is picked. That happens, because self.data is not assigned above:

https://github.com/apache/cordova-plugin-camera/blob/master/src/ios/CDVCamera.m#L380-L382

So, call to [self.data mutableCopy] produces nil, and the next call obviously fails:

https://github.com/apache/cordova-plugin-camera/blob/master/src/ios/CDVCamera.m#L599-L601

It seems that this issue could be easily fixed by assigning self.data = data in the mentioned code:

https://github.com/apache/cordova-plugin-camera/blob/master/src/ios/CDVCamera.m#L380-L382

Could you please take a look?

I too get an error return when I specify PNG on iOS.
The error also occurs on iOS 14.1.
Does anyone have a corrected version of the commit?
encodingType: camera.EncodingType.PNG,.

JPEG is specified, it works fine

The error happens for me with 7.0.0 but not with 6.0.0 tag
