Need help troubleshooting externaldata operator search

Christian Lozach 1

Below is the search. * included for obfuscation. I uploaded a file to Azure Storage and got the shared access signature.

externaldata(rulelabel: string) [h@"https://companyname.file.core.windows.net/?sv=*************"] with (format='txt', ignoreFirstRecord=true)
| summarize count() by rulelabel

But whenever I run this I get no results and the insatiably frustrating log analytics response of:

Some aspects of the query had errors so the results are not complete
If issue persists, please open a support ticket. Request id:*************

Where do I move from this? How do I begin to troubleshoot?

Any help is appreciated, thanks!

Are you using the SAS token to run the query/search? If so, where are you running query?

Can you provide any screenshots of this issue so I can get a better picture of what you're trying to troubleshoot?

Any additional information would be greatly appreciated.

Hi James,

Thanks for your detailed response. I have case 120120224004420 open for any information not wanting to publish on Q&A.

I am following the documentation of the externaldata operator https://learn.microsoft.com/en-us/azure/data-explorer/kusto/query/externaldata-operator?pivots=azuremonitor

I am using a SAS token and running the query on the log analytics plugin of Azure Sentinel.

I do not have any additional screenshots unfortunately, due to the error being very vague. I don't believe it to be a syntax issue as I'm sure the interpreter would be able to pass a better error if that were the case.
