Slack Websocket API - Warning message in Slack when actioning Buttons

[onestix]

Hi @guidone - I hope this finds you well.

I wanted to thank you again for having introduced the Slack Websocket API. It's been working really great for me so far.

There is however one tiny challenge I have and that is when implementing buttons, specifically when I click on them. I do successfully receive a "response" message in Node-red, but Slack however shows me a Warning message in the Chat UI:

I managed to find a ticket directly with Slack where this issue is also described:

slackapi/node-slack-sdk#869

Looking at the provided solution, I wonder if there is something that we are missing on our end, ie. confirming message receipt with Slack, once a button response has been received by Redbot? Or am I just missing a configuration on my setup?

My Node-red configuration looks the following:

1- Message is sent using a block:

2- Message (response, including blockid) is well received:

{"type":"response","chatId":"xx","userId":"xx","ts":null,"transport":"slack","inbound":true,"content":{"my_blockid":"my_value"}}

Thanks for your help and please let me know if you need further details.
