hi,
when using a barcode scanner in a “module”, the mapping of the result parameters (“text” and “format”) to a struct fails with “Uncaught Path points to undefined field.”
thx.

the problem is that you are trying to move the data into a structure wich has no default values for the fields.
You have to set a initial default value for all fields you want to access.
Here you can find a little video showing how to fix this.
