How do I get Wireshark to describe can-bus errors
I can see the can stream but there is no error details. Do I need another filter

A "filter" just filters out packets from the display; it doesn't add information, it just hides packets that don't match the filter, so you can see which packets do match the filter.
If by "can-bus errors" you mean CAN error frames, the filter you want is can.flags.err == 1
; that will limit the display to error frames.
If by "can-bus errors" you mean lower-level errors, those aren't saved in most capture file formats.

Is there another filter needed?
It's possible that there are no errors in your capture, or maybe error packets are dropped by your capture device.
