500 Perl execution failed Server: MiniServ/1.810

Tried to check “DNSSEC Verification” but get the following error:
Can’t use an undefined value as an ARRAY reference at /usr/libexec/webmin/bind8/conf_trusted.cgi line 71.
Any idea what could be wrong?

found the solution:
https://github.com/webmin/webmin/commit/031dd7653882e6defb33b40fd80465a4354822de
it is a webmin problem and will be fixed.

looks like somehow if i delete a domain, bind config does not get properly changed by virtualmin. Any idea?
