Argument value out of valid range

[t-o-o-m]

Unsing a raspberry pi zero with a ttyebus module, Wolf BM1 & CGS20. Running ebusd as follows: ebusd -f --scanconfig -d /dev/ttyebus --configpath=/etc/ebusd/ebusd-configuration/ebusd-2.x.x/de --mqtttopic=ebusd/%circuit/%name --mqtthost=192.168.XX.XXX --mqttport=1883 --mqttuser=XXX--mqttpass=XXX--mqttlog --accesslevel=* I get the following error:

[update notice] store 08 ident: ERR: argument value out of valid range [update error] unable to parse scan-read scan.08 from 3108070400 / 0a500106334202102d5130: ERR: argument value out of valid range [bus notice] scan 08: ;Kromschroeder; 3B ; [main error] scan config 08: ERR: argument value out of valid range [mqtt error] decode scan.08 : ERR: argument value out of valid range

Same without mqtt (- the [mqtt error] of course)

the answer from the slave is not specification compliant, that's why it is reported like that
