JiHong88 commented 2 years ago

Please let me know under what circumstances the error occurs.

This is still happening in the latest version:

"suneditor": "2.45.1", "suneditor-react": "3.6.1"

It happened when pasting an image from a screenshot, inside the editor.

We ran into this as well, it appeared when we had a tag like so in an email reply (munged by the user's email client): <img alt=\"image0.png\">

We think it's possible when that image tag fails to load because of the missing source, Suneditor should do a nil check or something before attempting to set attrs on it.

Please let me know under what circumstances the error occurs.

This is still reproduceable in the current version (2.47.0),

copy and paste html with an img tag (that has no style attribute) directly to the editor
switch to CodeView (codemirror is active, not sure if relevant)
switch back to WYSIWYG -> Error occures

Cheers.

Actually this is a real showstopper, since the error occures while the editor is initialized, thus no eventhandlers are added afterwards, what results in changes cannot be handled and saved. It's a deadlock situation in our application.

Please fix this bug or at least catch the exception, that at least the editor instance is returned for futher processing.

Cheers.
