September 2017 update bug. Unexpected error: Object reference not set to an instance of an object

[Fuzzy_Barsik]

After September 2017 update (2.50.4859.502) we've faced an issue similar to one some users had reported in February: when we try to get data from Analisys Services, where our MS Dynamics OLAP Cube is located, we end up with the following error: 'Unexpected error: Object reference not set to an instance of an object'. Rolling back to previous PBI Desktop version resolves the issue.

I was hoping this bug would be fixed in October update, but that didn't happen...

In case I didn't set it clear enough in my previous comment: nope, February update 2.55.5010.521 didn't fix the issue.

Hi @Fuzzy_Barsik,

Would you pleas share desktop trace log with us? 

Also would you please share detail steps how you connect to SSAS in desktop? 

Best Regards,

Hi @v-qiuyu-msft

No special steps, just select Get Data -> Analysis Services

Enter OLAP cube server address and select Import

If it's first time connection, enter login and password.

End up with the error message

Here are the trace logs.

And it has eventually been fixed. Hurray!
