When you access the error profiles in the Management page an error will appear:

"An error occurred in the K2_Management Service Instance. Object cannot be cast from DBNull to other types."


This is related to a new column added to: [K2].[Server].[ErrorProfile]
Column name: [ThresholdRule]

If the value is NULL then you cannot load the error profiles.


As a workaround, please update the ThresholdRule using the following script:

Update [K2].[Server].[ErrorProfile]

Set ThresholdRule = -1

Where ID = [ID]

The official fix will be included in the next update/FP.
