I had installed a private OBS server (2.9.6 appliance)on x86_64 machine and disable obs worker component, Meanwhile, I also installed a separate x86_64 worker on another machine and a arm64 obs worker on raspberry pi4, I configure obs server and these two separate obs worker(x86_64 and arm64 pi4) according to manual "https://openbuildservice.org/help/manuals/obs-admin-guide/" and "https://openbuildservice.org/help/manuals/obs-user-guide/" Meanwhile, the following content was gotten on dispatcher.log file on obs server "badhost event: home:<username>:<projectname>/hello/x86_64/x86_64:obs-worker-x86:1 Use of uninitialized value in concatenation (.) or string at /usr/lib/obs/server/bs_dispatch line 628. Use of uninitialized value in concatenation (.) or string at /usr/lib/obs/server/bs_dispatch line 629. " on obs worker machine, look up /var/cache/obs/worker/root_x, all debs(debian packages) may be made successufully. why does I alway get the ERRROR? Could you give me any help or advices ? I can registered two separate obs workers to obs server (2.9.6) and build jobs may be started (both arm64 and x86_64), but alway get the following hint on WebUI/API after I start debian package "hello" building "No live log available: package 'hello' has no logfile" Additionally,I also test 2.10.10, But I can confirm that it is problem about bs_worker, because I found a "Logfile is not that big" output from function 'stream_logfile()' in /usr/lib/obs/server/worker/bs_worker through looking up rep_server.log or capturing network packet by wireshark tools
