XML Attribute parsing failed exception thrown by SDK when trying to create a transaction

[rockers007]

I am trying to use this SDK to integrate bbpos Chipper 2x BT in my flutter app.
Everything listed below works fine:

• Detecting the POS device
• Connecting to the device
• Setting up UI configuration/Customisations for Inperson SDK

But when I try to create a transcation for purchase, I am getting following error:

I'd appreciate a quick response to this.
