When using the drawio, I got the error "Error saving file" when the drawing includes a jpg. The error occurred under the two cases:
1. copy and paste a jpg image from the photo viewer (I am using windows)
2. the jpg is an attachment of the same page, through the "+ > image" function in drawio interface
The error disappeared when I removed the jpg.
I can include png file in the two cases above (that is, "copy-and-paste" and "add image") with no problem.
Appreciate for any help. Thanks.
