Issue with Oracle Connectivity

Hi,

Up untill yesterday i could import data from Oracle Database. Last day i downlaoded the new PowerBI Desktop Update and since then i am receiving the bellow error everytime i am trying to connect.

 

Details: "An error happened while reading data from the provider: 'Object reference not set to an instance of an object.'"

 

Note: I am now connecting PowerBI from a different pc that has previous build, currently afraid of upgraing it, please advice as we are trying to go for production this week!!

 

Warm Regards,

Sami

I am having this same issue.PowerBIOracleError.png

 

I can reproduce this issue which seems like a permission issue to the oracle drivers via the Power BI Desktop client. If I change the permission of the application/folders it resolves this issue. However, I do not know how to correctly fix this permission problem without breaking the windows store Power BI App. 

 

I aslo, tried to debug the exe in visual studio, when I run the app in debug mode it doesn't have the issue.  I hope Microsft will fix this issue.

 

Thanks in advance!

Hi @samihuq,

 

Please verify you have installed the Oracle client software properly according to this article: Installing the Oracle client.

 

Also you can check this similar thread: PowerBI desktop 64Bit oracle connection error Object reference not set to an instance of an object.

Should I go ahead with a ticket on this issue? I haven't seen a response.

Sorry for belated responds. Please go ahead and close the ticket as i have moved away from Oracle Database to SQL Server.

Hi! How did you change the permissions to get this work? I have the same issue, where I installed ODAC into an existing client_1 as I have set up a test environment of Oracle database, and OBIEE Oracle BI, I had already another istance.

 

I have seen other threads about this error message saying it is mixing of 32 bit and 64 bit clients.

I had the same issue, Restarting Power BI to run as administrator resolves the issue.
