Post Message to Yammer

(2) ShareShare

Posted on by 183

I am using an approval workflow for questions submitted to Microsoft Forms to be approved/rejected. If approved, the Form response will be sent to a Yammer feed.

This was working fine yesterday, however today all of my flows are failing and even the previously successful flows fail. I haven't changed anything so I'm not sure what the actual issue is.

This is the error I get when the Action 'Post_message' runs:
{"group_tags":["Unable to fetch group tags"],"code":"unknown_error"}

The Yammer group is still there and is set to Open permissions for posting during testing. And the service account posting is a part of that community as well as being an admin.

    Hey - sorry I can't offer help but just to one-up this post as having the exact same issue, starting today as well. Same error and no resolution via re-authenticating the connectors. We recently completed our transition from 'Yammer' to 'Viva Engage' and I wonder how much that might have to do with it, albeit as I say all of the connectors appear to be linked up correctly and showing up within the actual flow builder. Even a simple test flow is struggling on the 'post' action, regardless of group or content.

    I just ran into this myself and found your post when I searched. I got the same message in a test group that created just today. 

    It looks like the connector tries to enumerate the "Topics" in a group when performing the Post message action. I added a Topic to the group by creating a post and then selecting "Add topics" from the overflow menu on the post. 

    It appears Topic is synonymous with Tag in this context. Once the group had at least one Topic/Tag, even if it was no longer associated with a post, I no longer received this error.

    Seems to be working now. Again, I didn't change anything, my guess is the change from Yammer to Viva Engage is having some issues.
