An error occurred when exporting with the plugin in 2025.3

Hello there!

Sorry for the late response, but I believe that you should be able to replace this line:

this.sketchObject.CSSAttributes()

with this:

this.sketchObject.CSSAttributeString().split('\n')

which will produce essentially the same results. See also Function to get CSS Attributes removed from API?

Let me know if this works for you!
