I am using 'com.github.yalantis:ucrop:2.2.1-native' library for cropping the image

        try {
            photoFile = createImageFile()
        } catch (ex: IOException) {
            // Error occurred while creating the File

Answer 1

java.lang.IllegalArgumentException: Parameter specified as non-null is null:

hardly to say which one exactly is null. For instance

public override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent) {

the Intent could be null, and it should be marked as nullabe. Change it with

public override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
