Slack blocks kit api error

I am working with an ActivePiece to send a slack message to a channel using the slack block kit. I have tested the block in the Slack Block Kit Builder.

{
	"blocks": [
		{
			"type": "image",
			"title": {
				"type": "plain_text",
				"text": "This is the message above the image"
			},
			"image_url": "https://url",
			"alt_text": "random title"
		}
	]
}

Given the above structure, the image and message work fine from within the slack block builder when tested.

When I copy and paste the working code over to ActivePieces and run a test I get the error message:

"An API error occurred: invalid_blocks_format"

I found a github issue that describes what appears to be the same issue:

When I attempt to remove the blocks key as it suggests in the issue, I get a validation error from the Piece which no longer allows me to send a test.

Is there a working example I can test with from within ActivePieces?

Hello @SteveL , Welcome to the community :wave:,

Please pass the value of the “blocks” key directly in the step; this will result in the following.

[
	{
			"type": "image",
			"title": {
				"type": "plain_text",
				"text": "This is the message above the image"
			},
			"image_url": "https://cdn.activepieces.com/pieces/slack.png",
			"alt_text": "random title"
	}
