Did you check you access rules of Scan_data and nanaflow allowed roles? (and double check if the object is perhapt really empty when passing it)
Hi Pim
I am using security off. And object is empty when passing. I am posting pictures of model and nanoflows.
Error is occuring when executing Show Message with parameter $Scan_data/ScanValue calling nanoflow On Scan Event.
With microflow call parameter $Scan_data/ScanValue is displayed without errors.
Note* Entity Scan_data is non persistable
