pasting image bug?

[LaysDragon]

Here is something strange,looks not like all kind of copy & paste image can operating successfully.
When I copy an image from QQ,it just throw Uncaught TypeError: Cannot read property 'name' of null to console and nothing happen.
The script can recognize the pasted object as an png file.But when it trying to getAsFile() it just failed and return null.
Here is an screenshot of the debugging on chrome.

The code itself is definitely not the problem.

Works fine with latest Firefox and Chromium builds.

Can you please provide some information about what Chrome version you are using? Also a like of a picture you tried to use.

This would be very helpful

chrome version:62.0.3202.94
Any picture copied from QQ software.The marked option in picture mean copy.

Looks like there is some kind of limit to paste a image from clipboard.At least not all kinds of clip data.
It should prompt an error when image upload failed.Not just stuck a text in editor and let user wait forever.

This appears when the picture that is copied doesn't generate some kind of file. In this case getAsFile() returns null.

I'm currently not sure where we want to handle this but probably I'll simply add some error handling for this later.
