Teams Image sent by chatbot no open after update

Occasional Contributor

@HunaidHanfee-MSFT Hello, we had the same problem, but as of today without making any changes with the teams version of 7/10/2021 the images began to be sent correctly, but when clicking on them they do not open, on the web and mobile app open correctly


teams desktop



Teams Web




I do not have a previous version available to test, but this worked and it stopped working a few days ago together with the shipment without any change on our part, any ideas

Thank You

Thanks for sharing. I am looking into this, I will get back to you soon.
The image is sent as inline attachment?

@HunaidHanfee-MSFT Yes, we send it as an inline attachment and we have also tested with the public url in both cases the behavior is the same

I share some images:


method call



return GetReport



Inline test (microsoft example)




the bot returns the image but it cannot be opened, this verification only occurs in the desktop teams client, in the web and mobile client it opens correctly
