I upgraded one of my test Proxmox node to 8.2.2 and since then I am seeing the following error on Ceph > Monitor dashboard.

Code:
malformed UTF-8 character in JSON string, at character offset 1093 (before "\x{fffd}/\x{64f}\x{fffd}...") at /usr/share/perl5/PVE/RADOS.pm line 277, <DATA> line 960.

The Ceph cluster is functioning fine, there is no MON error in the Ceph or Syslog. I just cannot do anything related to Ceph MON. Any command I apply to add or remove MON spits out this error. The GUI also showing the same error and MON portion in the GUI is inaccessible.

Ceph is running reef.

Note: All Ceph portions in the node had been working fine up until the latest update. Anyone else saw the same or similar?
 
could you check which of the API requests triggers that error (the browser dev console should show you).
