Value cannot be null. Parameter name: stream

[SamualDaxter]

Hi Everyone,

I'm getting the following error when I open a pbix file in the August 2020 (2.84.981.0)

Value cannot be null.
Parameter name: stream

Is there any way I can get round this?

Is there a fix out there for this ?

It seems to be an issue with August's release, the dashboard was working fine in the July 2020 version.

Thanks for your help.

I apologize for the incorrect date above. This was fixed in october and should roll out in the November release of desktop. 

Till then, as a workaround, you can try doing

File -> Options and settings -> Options -> Data Load (under global) -> Folded artifacts cache options -> clear cache

This should clear and regenrate the cache. (the error occurs when trying to read the cache.)

thanks

This issue should be resolved in the November release. Please let me know if anyone encounters this after that.

Hey,

Yes i did add an updated comment with the workaround. 

I added incorrect date. the fix was made in october and should roll out in november release. Meanwhile you can try the workaround to unblock yourself.

Hi,

My source is a SQL on premises direct query, so it took me a while to open the data set. but...

The workaround you suggested it's working!!!

Thanks so much!!!

I'll wait for the November update for the final fix.

I still see this issue in the October release. My version info is:
Version: 2.86.727.0 64-bit (October 2020)

Am i missing something?

Thanks

Same here. Since last release. On a report with a streaming connection to a SQL database. The error message pops up continuously which prevents me from being able to edit any report settings.

I've upgraded to the September release of Power BI and do have the same issue in files with direct connections to an Azure SQL db: "Value cannot be null. Parameter name: stream" 😒
