Teams - Post message as the Flow bot to a channel is blocked by user

(1) Share

Report

Posted on by Community Power Pla...

We have a Flow that is set to have a Yes/No condition based on a variable that depending on it will send to one of two channels in our Teams org.

With the new channel we've added, it's failing with error:

"error": {
"code": "BotRequestFailed",
"message": "Request to the Bot framework failed with error: '{\"error\":{\"code\":\"ConversationBlockedByUser\",\"message\":\"User blocked the conversation with the bot.\"}}'."

The channel has "allow bots to submit channel messages" and "allow connectors to submit channel messages".

Any help would be much appreciated, thanks!

Hi @Anonymous ,

From the error message, there is indeed a user blocked the conversation with the bot. Please check again if there is such a situation.

Then you can try to recreate the connection and configure Flow.

Best Regards,

Hello,

I met the same problem. How can I unblock "MS Flow" in Microsoft Teams?

Hi @ChristianAbata,

thank you for trying to help but I do not understand what exactly should I do.
Note that I do not need to "unblock a user", I'm trying to unblock the Flow app and after clicking "Unblock" nothing changes:

Thanks again.

Any chance this is happening because it is a private channel?

I am getting the same error, but Flow is unblocked, and I continue to receive the error.

Here's the fix that worked for me.

Go to Teams Chat, and search in Chat up the top, search for "Power", and the Power Automate chat message should appear, click the three dots and unblock. See screen shot below.

My flow is working again. I certainly didn't block the Power Automate chat, so I'm not sure how this happened.

Hope this helps others!

Had the same error:
Request to the Bot framework failed with error: '{"error":{"code":"ConversationBlockedByUser","message":"User blocked the conversation with the bot."}}'

Solution was simply to install the power automate app from the teams app store.

After installation the error disappeared for users that installed the app.
