No what actual barcode did you scan? What was its value. Do you have a photo of the barcode?

Also, show us the value as it arrives ( before it is processed by any other nodes)

Ps, in your screen shot, buffer parser is not connected.

If you want accurate help, accurate & complete info is necessary.
