Error - : "AnalysisServices: String reference not set to an instance of a String. Parameter name: s
Hello Guys,
I have some datasets that I got from Analysis Service. I try to refresh those datasets and it gives me an error. This happens last Friday. Before that, it works totally fine. I have the same Power BI version and the same dataset on my Laptop. It will refresh fine. This only effect on my Desktop. Please see below for the error.
I try to reinstall power bi, downgraded and try to install the latest version. Still not working.
Can anybody please tell me what is this or is there anyone I can contact on Power BI technical side?
Thank you
DHana

For some reason I cannot post an answer, so I'll keep it short this time. Just "Clear Permissions" HOME>Edit queries> clear permissions

Hi DHana,
Did you send any customized query to the Server?
How can I reproduce this issue?
Did you have the latest version of the Desktop?
It seems an issue of SSAS. Please refer to Forums/en-US and string-reference-not-set-to-an-instance-of-a-string.
If you'd like to contact Power BI tech, you can file a support ticket here.
Best Regards,
Dale
