I can no longer save my file, svg to HTML Canvas. I receive this error message:

In Swedish it says that "Inkscape has received additional data from the script that was run. The script didn't return any errors but this can give unexpected results." The following thread gives no solutions: https://inkscape.org/pt/forums/questions/error-when-using-extensions/

Please report bugs at https://inkscape.org/report (and make sure that you're using the latest version, too). And perhaps try if it works without swatches or gradients to narrow down the problem.
