Error when Refreshing Data

[New2PowerBI]

I am receiving the following error when I try and refresh my data:

Failed to save modifications to the server.  Error returned: ‘An unexpected error occurred (file ‘tmtransaction.cpp’, line 5975, function ‘TMTransaction::GetProxyFromPrevSavePoint’).’.

Did not find a similar error in discussion boards; any thoughts?

@New2PowerBI,

Which data source did you connect? And which mode did you used, import or directlyquery? One situation is that your pbix file is less than 1GB when importing it to Power BI service, but the data model grows beyond 1 GB after a period of time, you will get a error when refreshing the dataset. 

Or you can capture the following logs while recreating the issue. 

Fiddler Trace

============

1. Install Fiddler from http://www.telerik.com/download/fiddler/fiddler4 if not already done
2. Launch fiddler, then click Tools > Fiddler Options
3. Click the ‘HTTPS’ tab.
4. Verify the options are set as shown in this screenshot:

5. If fiddler prompts you to trust their root certificates, then click ‘Yes’.

6. Then navigate to repro the problem while fiddler is capturing traffic.

7. After the trace is captured, go to File > uncheck box next to Capture Traffic

8. File > Save > All Sessions and post it here.

Regards,

Charlie Liao

As if by magic my issues have been resolved.  I was told by our IT department that there was a Power BI SCCM package and all errors I had been receiving were taken care of.  I've refreshed and republished multiple times since with no errors.

Thanks; I don't have Fiddler and I need admin rights to this PC in order to do so.  I'll work on getting that installed and recreating issue to post here (likely early next week).
