saveXML(): Error when using an extension

I’m having this error (Error: no namespace uri given for prefix ) when I save the xml, for the following function:

modeler.saveXML({ format: true }, function (err, xml) {});

Can someone help me?

If you remove the extension the saveXML() function works. but with the extension it doesn’t.

Not sure what that CodeSandbox is supposed to demonstrate. You’re exporting before the import has even finished. Can you fix the CodeSandbox so that it reproduces your issue?

Sorry @philippfromme,
I have already managed to solve the problem,
The problem was in the json file of the extension, uri was wrong. Thanks!
