Hello,
I am developing a power automate flow that triggers from a power virtual agent. In the PA flow, I am trying to send adaptive cards to the users who invoke the bot and wait for their response. This flow is working well in the test mode of PVA, but once I publish the bot I am getting: Sorry, the bot can't talk for a while. It's something the bot's owner needs to address—error code: 3002.
Below error was thrown in the PA:
The execution of template action 'Return_value(s)_to_Power_Virtual_Agents' is failed: the client application timed out waiting for a response from service. This means that workflow took longer to respond than the alloted timeout value. The connection maintained between the client application and service will be closed and client application will get an HTTP status code 504 Gateway Timeout.
found very usefull topic with workaround
i have the same problem.. sending to user two adaptive cards mid-conversation
when flow is triggered first adaptive card is successfully send to user. Even if its submitted in 5 seconds, it shows "Your response was sent to the app" and waits two minutes for timeout. After 2 minutes error message is shown but the flow continues and second adaptive card is displayed. After submitting the second one, it is confirmed right away (no delay or timeout) and mail with data is sent correctly. If i change the order of adaptive cards there is again same error after the first one so the order change nothing.
If i delete second adaptive card, timeout for the first one is still there
Is there any way how to fix this?
Sure. Here are the step in the production PVBA bot we have:
1. User issues command "send message." The PVA topic calls a flow., That flow presents the user with an adaptive card.
2. User fills in the adaptive card and hits "Submit for Approval." Notice the flow/bot responds "your response was sent to the app." But the adaptive card doesn't go away and provide the submission message.
3. Observing the in progress flow, it looks as if the flow is awaiting a response. Yet, user has pressed button.
4. The bot eventually shows the submission message and an error message.
Sorry, the bot can't talk for a while. It's something the bot's owner needs to address. Error code: 3002. Conversation ID: xxxxxxxxxxxxxxxxxxxxxxx. Time (UTC): 3/25/2023 3:48:18 PM.
If you look at the flow, it looks like the adaptive card submission worked fine. The flow continues and completes all other steps successfully.
It seems the "post adaptive card and await a response" step takes 2 minutes every time, which I think is the default timeout.

@terzogenito , can you share more detail on your scenario and what error you are seeing? It will be really helpful to have screenshots too if they are available.
@Keshav07 - how did you ultimately solve this issue? I have the same issue. It actually works fine and as expected in the Power Virtual Agents test mode. When I publish and initiate from production PVA bot I get same error.
Hello, Thank you for the help. Yes, the bot is able to send the card to the user. Even after the user responds the flow will still be stuck waiting for a response for 2 mins and then it gets a time-out error.
Was the card sent successfully to the user? When a flow is called from a PVA bot there is a 2 minute timeout when the flow does not complete in time. I speculate the card was sent but no button was clicked within 2 minutes that caused the flow time out.
In addition, if your scenario is to send an adaptive card to user during mid-conversation, it is recommended to use Bot Framework Composer for it and not use PVA bot to call a flow to send an adaptive card. This is because Power Automate has throttling that would impact end user experience if many users are chatting with the bot at the same time.
