buildinfo invalid - how to fix

It looks like some metadata is invalid for my project, at least locally. For a local build I get:

rger@localhost:~/osc/home:rainergerhards:branches:home:rgerhards/rsyslog> osc build xUbuntu_19.10 x86_64
Building rsyslog-xUbuntu_19.10.dsc for xUbuntu_19.10/x86_64
Getting buildconfig from server and store to /home/rger/osc/home:rainergerhards:branches:home:rgerhards/rsyslog/.osc/_buildconfig-xUbuntu_19.10-x86_64
Getting buildinfo from server and store to /home/rger/osc/home:rainergerhards:branches:home:rgerhards/rsyslog/.osc/_buildinfo-xUbuntu_19.10-x86_64.xml
buildinfo is broken… it says:
unresolvable: nothing provides rzsz

The same platforms builds without problems on the OBS web builders. I also have nowhere defined a dependency “rzsz”. Does anybody know how to remove this invalid piece of metadata (or whatever it actually is)?


PS: Here it builds:

I personally just delete the local build folder and just osc co again. Maybe not the best method but it work for my case.
