Can no longer connect to Azure Data Lake Gen 2

[WomanToBlame]

Hello,

My data source is ADLS Gen 2, which was working find up until September 16. Now I get a non-descript error when trying to connect to the datasource from Power BI desktop. The published report is refreshing without an issue, so it seems specific to desktop.

Feedback Type:
Frown (Error)

Error Message:
Error

Also, when trying to refresh the data in desktop, it gives this error:

Could not load file or assembly 'Microsoft.Mashup.Cdm.ICdmProvider, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.

Any help would be appreciated - I'm supposed to get this report out and I'm dead in the water!

Hi  @WomanToBlame 

Can you create a new report with Azure Data Lake Gen 2 normally ? Or does this problem occur in the specified report ?

Hello Ailsa Tao,

It also happens when creating a new report. This is specifically when using "CDM Folder View". "File System View" connects. I believe the error message below is the heart of the issue, but not sure how to remedy it. I've opened a MS support ticket.

Could not load file or assembly 'Microsoft.Mashup.Cdm.ICdmProvider, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.

Any update on this issue; I am also encountering the same issue and get the same error. 

Brand new file connecting to Azure Data Lake Gen 2 in PBI Desktop with CDM.  "File System View" works correctly as does using CDM in dataflow on app service.

Hi @brendan_w_FWM ,

It suddenly corrected itself yesterday. Both CDM view and refreshing is working now.  Not sure if maybe a hotfix was pushed out. I'm currently on version 2.121.762.0 64-bit (September 2023)

* I see in my initial post that I encountered this issue on 2.121.662.0

I am experiencing the same issue and it is of course blocking me on delivering a report to a client. I tried uninstalling and reinstalling Power BI which did not fix the issue.

Can you guys PLEASE stop release updates with big bugs in them? There are a ton in this last release. We are not your guinea pigs guys. We are serving clients and many of them are cranky excutives.

I am having the same issue, if anyone managed to find a solution please let us know 😰

[brendan_w_FWM]

Thanks @WomanToBlame for the reply. I upgraded to 2.121.903.0 this morning and the issue is fixed. I was previously on 2.121.782.0. 

Hope everyone else get's the issue resolved soon!
