Tap on viz dashboard failed

[gxf1027]

Hi,
when I click on tap cion on viz dashboard website, a blank page is returned without any information.
However, 'kubectl auth can-i watch deployments.tap.linkerd.io -n emojivoto --as $(whoami)' returns 'yes', and other features on dashboard is just ok.
Could you give a help.
Thanks a lot!

it works with command line, but it doesn't work with dashboard.

This is likely tracked by #9306.

Thanks a lot.
When '2.11.4 stable' is used, tap page works.
