panic: could not generate default trust domain: error generating default trust domain from root CA: no root CA detected after chain assembly from the root identity server cert and ca bundle
This is a new issue. A recent release made this field required.
Find your controller config file and add a top-level-entry such as:
trustDomain: any.value.you.like.here
We're still working through the change to HA controllers and now-a-days, a trust domain needs to be specified. It can be whatever you like it to be. Once we get further along, this config item might become unecessary but for now, you should be able to add that entry and get back running.
