Error Message Cannot access a disposed object Object name SslStream

[Daryl-Lynch-Bzy]

Hello

I am receiving this error message while refreshing a Power BI PBIX in Power BI Desktop.  The PBIX file is reading data from various Power BI Dataflows.  The Dataflows and Dataset are hosted in EM1 premium capacity.  The Dataflows and Dataset are refreshing normally in the Power BI Service, I am only encountering the error message when refreshing in Power BI Desktop.  This is happening on two separate computers.

The size of the Power BI pbix file is 17MB, approx 30MB in Vertipax Engine.

Feedback Type:
Frown (Error)

Error Message:
Cannot access a disposed object.
Object name: 'SslStream'.

[SamyakJain]

PR has been merged and This will arrive in SU06.
for now the possible workaround is to download the DEC21 version of PowerBI.

Thanks!

[lbendlin]

Same issue when calling gateway connection status from the PowerBIRESTAPI custom connector.  What does "SU06"  mean?  June 2022 ?

[Lachlan_Duncan]

This is clearly not just a one person user error.  calling it as it is, this is a bug 

Migrating back to an older version is not feasible in many organisations (like where I work) with central controlled version  installation.

Please advise on when this will be fixed.

[mamsteroonie]

Please give an update on this issue.  It's stopping our work.

[SamyakJain]

Good day, everyone!
This issue will be fixed in the PBI desktop version releasing in June2022. It'll most likely be released around the middle of June (around 15 -17). 

Possible migitation is to download the December21 version of PBI Desktop. you can find it on:-Previous monthly updates to Power BI Desktop and the Power BI service - Power BI | Microsoft Docs  

[Daryl-Lynch-Bzy]

@SamyakJain - thanks for the update.  I hope the update will resolve my issue. 

[lbendlin]

Confirmed fixed - thank you!

[Daryl-Lynch-Bzy]

@SamyakJain - the latest update appear to have fixed my problem.  Can you please update the status to Resolved?

I have the exact same issue with Power Query in Excel. Started mid july. Using exact same file that was working on July 12th and now, when trying to refresh queries, I get this:
