file.content.substr is not a function

Bug

What is the current behavior?

Error is thrown when saving object instead of string on file.content during upload callback.

What is the expected behavior?

@mrheault We are expecting file content here, base64 string.

Thank you, Andrew

Can you make it clearer on how to fix this issue please? If the input could be illustrated with an example it would be better. Currently I convert to base64, however anything beside images doesnt appear.
