connection error on Victron Smart Shunt - ERROR [sampling] solarCharger error: <class 'AssertionError'>

I am successfully monitoring two Liontron batteries at the same time using your app. thanks again for your work!
I now tried to connect a new victron smart shunt that i recently bought. I always get the same error. It seems like its connecting successfully but than fails to parse the data froms the device.
what i tried:
tried to fetch data from all three devices at the same time
tried to fetch data only from victron smart shunt
renamed the device
change the pin code
bt_power_cycle: true/false
install_newer_bleak: true/false
any ideas?
