MessageCard OpenUri showing blank tooltip, how can I hide or populate it?

Copper Contributor

Hi -


I have an integration app that sends messages using the MessageCard template. It has some potentialAction buttons.. however, those buttons have hover text which shows up empty. Is there any way to hide this hover text/tooltip or populate it? Is there a field in the JSON that I can add?

This is only a recent change with the latest Microsoft Teams desktop app (Version 23320.3107.2575.3762):

Please let me know if there is anything else you need to help figure out this issue. Thanks!

The json for this button is:

"id": "button_section",
"potentialAction": [
"@type": "OpenUri",
"name": "View",
"os": "default",
"uri": ""

@Meghana-MSFT Thanks for looking into this! Please keep me updated!

Is this fixed? Seems like I can't reproduce it anymore.
