Environment

SPE 9.3.0
Windows Server OS

Cause

This is happening due to SPE server sending blank string in response to rest API request for GET_RESOURCECONSUMPTION.

The difference between the attribute when SPE server is preparing the response also causes the issue. The response code is sent as 200 but due to the empty data being returned, the UI ends up throwing the error.

Resolution

Currently there is no workaround available for this issue as it is coming straight from the SPE server.
A fix will be released with SPE 9.3.1 version.
