502 Bad Gateway when posting adaptive card to Teams

Posted on by Community Power Pla... Microsoft Employee

I have several flows which post adaptive cards to Teams. All of them suddenly stopped working today, giving me a 502 when the flow attempts to post the adaptive card. I created a simple flow to test this, which just posts a basic card to myself. This simple flow also gives me a 502. Any idea what's causing the sudden issue?

Hi @Anonymous

Thank you for posting.

According to your description, your flow used to send adaptive card to teams suddenly failed and gets 502 error.

If the error code 500 or 502 appears, the failure is temporary or transient. Please click or tap Resubmit to try the flow again.

More details about troubleshooting a flow, please check it at here:

Since you didn’t mention your flow details, I create a flow using official example(https://docs.microsoft.com/en-us/power-automate/create-adaptive-cards-teams ) and it works fine.

Hope the content above may help you.

Thanks

Hi Anna

can you put an approximate timeframe on these 'transient/temporary' 500's & 502's? I have been experiencing this for more than 24 hours now.

Hi @generic_name

Thank you for your attention.

Unfortunately, there is no more information clarified from official documentation. I couldn't tell how long it will take to recover. In the most scenarios, the issue happens due to server incident. There is nothing we can do from customer side except waiting.

If you still worried about it or would like a quicker repair. I recommend you go to below website and request a remote troubleshooting to double check.
