removing the
min_len
parameter from https://github.com/HeinleinSupport/check_mk_extensions/blob/dbbcac92ac4f328cc060995c4adc58d2b8ffdd6a/sslcertificates/web/plugins/wato/check_parameters_sslcertificates.py#L28 is a workaroundI'm not sure if this is a result of this but it also failed to migrate the configuration for me when updating from checkmk 1.6.0p19
Another note: https://exchange.checkmk.com/p/sslcertificates links to https://github.com/HeinleinSupport/check_mk/tree/master/sslcertificates which does not exist anymore, instead it should link to https://github.com/HeinleinSupport/check_mk_extensions/tree/master/sslcertificates/
