Image Picker using React Native (Native module)

Question

I trying to build a native module module using kotlin for picking image from gallery, then crop it and display it in app. I have wrote code for picking the image and cropping, but when trying to send the cropped image using promise from native side to react native part, I am not receiving anything from the native side. if i send any string it is working but nor image. here is my image of onactivity result code

how can i get cropped image from the intent and send the result image to the react native part??
