I have some troubles understanding the ingestion of JSON entries (from Event Hubs) into Kusto / ADX. I seem not to be able to get the GetPathElement transform statement to work. I'd expected that something like
[{"test":"name","path":"$.content.something","transform":"GetPathElement(0)"}]
would work (according to documentation). Unfortunately, I get the (imo) undocumented error:
Value 'GetPathElement(0)' used in a switch/case is invalid
Can someone give me a hint/example on how GetPathElement should work?
