Web2Print: Inline Edit does not work

[polymed]

Hi guys,

I am trying to get the Web2Print function to work. I have used the examples from the Pimcore demo version. But something is still missing! Does anyone have an idea?

Best regards

Pimcore Version: 6.8.8

Result in the Database:

documentId,name,type,data
