Export Image and sent to a MS Teams Chat

Posted on by VM-22010656-0 5
Hi All,
 
I have a Power automate flow
Trigger - When an email is received
Gets the attachments (all images)
Send the attachment as an image in a MS Teams chat.
 
The problem I am getting is that MS Teams is recognising the image as binary and throws an error entity too large.
 
I have tried base64 and datauri conversions and still get the same error.
 
I have tried various approaches
- Saving the image in a onedrive folder then picking it up and trying to send it that way.
- Tried using an adaptive card
 
Does anyone have any workarounds?
Thanks in advance

    HI ,
    You can try using the Team Http request for this scenario.
    As this is a expected error by Power Automate teams connector , the entire message payload should be less than 28 kb.

    link to refer:  https://learn.microsoft.com/en-us/connectors/teams/?tabs=text1%2Cdotnet#known-issues-and-limitations-with-actions:~:text=Long%20description-,Message%20size%20limit,-Post%20adaptive%20card.
     
    to overcome these limitations , try calling graph api to send the message.
