Google Analytics Connector in PowerBI Desktop

I've recently installed November update for PowerBI Desktop and the Google Analytics connector has stopped working.

Am getting error message "Unexpected error: Collection was modified; enumeration operation may not execute."

Any advice?

Heya, I'm having the exact same issue.


Hi all, 


I'm not reproduce the issue in Power BI desktop November version. Please run fiddler with below option enabled, then repeat steps to reproduce the issue, save all sessions to .saz file, upload it to your OneDrive or dropbox, send the share link to me via private message. 




Best Regards,

Hi, just to add, i'm also seeing the same issue.  I can't retrieve any information from our Google Analytics Account. SQL is still fine.

Same thing for me. Dashboards which are live are updating well, but on pbi desktop i cannot refresh without warning /cannot work at all with GA data

I'm having the same problem, worked before yesterday without a problem. I have the November 2018 Power BI version.


Worked fine this morning - did the update and same as everyone else, no longer works.

Doesn't work anymore... Can't pull GA data either

Hi I had the same issue after the Nov update. I went to file > options and settings > data source settings and removed the GA credentials. This forced a re-authentication with GA and everything then worked.

Thank you WillHopkins, that worked for me as well.
