Hi.
I am trying to append a Puck.js experiment to add a View that displays the angle of inclination of the Puck assuming the x-axis of the Puck. After fiddling with the initial experiment, I am able to Generate an experiment QR code, but Phyphox on my phone gives an exception "Line 27: Tag needs a conversion attribute."

What is wrong?
Code:

Thanks for your report. The new editor apparently omits the “conversion="string"” attributes in the generated file that are present in the original files. We are working on a fix.

For the time being you need to manually add it to those “config” elements that do not have the mandatory “conversion” attribute.
