Hello Shahnavaz Kazi
It seems that the value for the CalloutUriRegex
property is incomplete.
Example:
"CalloutUriRegex": "sqlname\\.database\\.azure\\.com/?$",
In this command, replace sqlname\\.database\\.azure\\.com/?$
with the regular expression that matches the URIs for your external data sources.
I hope this helps you resolve the issue with updating the callout policy for your Azure Kusto cluster.

I hope this helps.
