I need your help. Using node-red-contrib-fritz NodeRed 2.2.2, FB 7490 with FritzOS 07.29. Trying to make a call "urn:dslforum-org:service:X\_VoIP:1" -\> "X\_AVM-DE\_DialNumber". While this works well from an ESP8266 unit (so configuration on FB is fine) I run into consistent errors ("Action failed with error: TypeError [ERR\_INVALID\_CHAR]: Invalid character in header content ["authorization"]").

Same happens on other services (e.g. GetDeviceInfo).

Does anybody have an idea what the problem might be?

BTW: The module pallette shows a warning "Assertion failed".
