Fatal native error: ReactNativeBlobUtil request error: Value for <key> cannot be cast from ReadableNativeMap to Stringnull #472

Description

version: 0.24.9
react-native version: 0.83.4

We had some production issue where our app had a native crash when trying to open a PDF file with the fetch function. In the end the reason was that an request header was transformed to an object instead of the string that the module expects. This is an issue at our side.

I hope that you can add some error handling in the module so that we can catch the error in the JS bundle when something goes wrong here. On iOS we could not see the error it just crashes. On android we saw the error and we traced it.
