KeyError: 'Processor' for /proc/cpuinfo

[anoymouserver]

On my Raspberry the ext-respondd currently aborts after startup and reports:

Apr 15 18:25:36 ffplieningrpb4olv6a systemd[1]: Started ext-respondd (respondd status for servers).

The syslog said something about KeyError: 'Processor' well in the /proc/cpuinfo it is also written in small letters: processor, so I made a small adjustment in the /opt/ext-respondd/lib/nodeinfo.py:

    if 'model name' not in ret:
      ret["model name"] = ret["processor"]

and the ext-respondd runs again.
