Yammer new "All Company" message: BadRequest Http request failed: the content was not a valid JSON

[hvandekamp]

When a new Yammer message has been posted to the "All Company" group / feed, I want a flow to be triggered.

To realize this I've created a new flow with the Yammer connector's trigger called "When there is a new message in a group", which asks me to enter a Group ID and select a network. Selecting the network works fine, but the group selector doesn't show the "All company" group:

• When I bind it to my network and to a custom created group, the flow works perfectly.
• When I enter Group ID 0, which perhaps would be right one according to online blogs, the Flow validation returns the error: BadRequest. Http request failed: the content was not a valid JSON.

See the attachment regarding the setup and error message.

How can I fix it to make sure the flow fires when a new message inside the All Company group has been posted?

Hi @hvandekamp,

Does the “When there is a new message in a group” trigger fires when you set the Group Id to 0?

I have made a test on my side and the flow doesn’t trigger. The flow works well when I bind it to a custom created group. 

There is no way to trigger the flow when a new message is posted into All Company group in Microsoft Flow currently,  if you would like this feature to be improved soon, please submit an idea to Flow Ideas Forum:
