Flow posting unwanted MS Teams posts

(2) ShareShare

Posted on by 4
Hi,
 
I've built a pretty simple flow that incorporates....
 
When a new [MS Teams] Channel message is added >> Post [MS Teams] message in chat or channel
 
The action uses the Message Body from the trigger post plus one additional line of plain text.
 
This was working fine, but recently it has started to post to the destination channel just the additional line of plain text when a new user is added to the channel used in the trigger. 
 
I only want the flow to post when an actual message is posted into the channel defined in the trigger. I added a condition into the flow, checking if the message body is empty, if it is do nothing, if not post - but it is still posting just the single line of plain text when a new user is added to the channel.
 
Is this as designed, am I doing something wrong?
 
Thanks in advance
 
Steve

    Hi,
     
    I think you can add a trigger condition to prevent the flow from running on specific types of messages, in settings.  You will have to experiment with the condition but the easiest way to do this is add a filter array to get the format right.  When you are done, delete the filter array action; you are only using it to get the format.
     
    In this example, I am checking the message type.  Again, review other dynamic content and find the one that works best for you
