Solution

 

Compare configurations on SWA for the non-working router to other routers listed and they are the same.

 

No issues were found with the KV store on vSWA and the KV store shows no errors.

 

The last telemetry update from the router was almost a couple of weeks before the upgrade

 

Upon further checking found that the Junos version on the MX was 21.4R3-S3.4.

 

Juniper changed the telemetry messages format which the vSWA could not parse and hence they had to release an updated MX version to 22.2R3-S3 and 22.4R2-S2 that could parse the messages correctly
