getBlocksData

Hello!
We are having a problem connecting FB to Slack
I admit that I searched the forum for answers and the given solutions (transform to json) don’t work, we continue to get the same error. can anyone direct us what we are doing wrong?

Hello there,

looks like you are trying to create a Block without having it formatted properly first.

Either use the Text field to directly send an unformatted message, or have a look here how to format the Block of the message correctly.
