OLE DB connection - no error message available

[odumna]

Hello

I have a report with OLE DB connection to powerbi dataset.
example of string connection is next:

provider=MSOLAP.8;initial catalog=sobe_wowvirtualserver-xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx;data source=pbiazure://api.powerbi.com;mdx compatibility=1;safety options=2;mdx missing member mode=Error;identity provider=https://login.microsoftonline.com/common, https://analysis.windows.net/powerbi/api, xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx;update isolation level=2

this report was working and refreshing  fine on desktop and portal.

But now I need to do changes in this report and in desktop I get error "Datasource error OLE DB no error message available, result code -895352820(0xCAA2000C)"
I tried to find solution by myself and I found that if delete from connection string phrase "sobe_wowvirtualserver-" all works fine in desktop, but once I publish report to portal I needed create new gatway.

On portal report is still working and autorefreshing fine.
How can I fix issue and use  initial connection string ? OR How can I change existing getway?

Hi @odumna ,

I can't reproduce this kind of error for the time being, can you provide the test file for me to do further troubleshooting?

Looking forward to your reply.

Best Regards,
Henry

As result issue was resolved by installing older driver x64_15.0.2000.558_SQL_AS_OLEDB
instead of the lastest x64_16.0.519.0_SQL_AS_OLEDB.
Once driver x64_15.0.2000.558_SQL_AS_OLEDB was installed all works fine.

Hi Oduman

Can you provide a link to download this driver please? I can't find it anywhere ( x64_15.0.2000.558).
