Using POST with Send request via HTTP doesn't work well

[Mieko]

Hi, teams. I want to use [Send request via HTTP]App to send messages to the Slack incoming webhook.Since icon_emoji and username are required, I am using HTTP request instead of Slack Post APP.I have completed setting up an incoming webhook in Slack and completed setting up Connection in Workato.

When I run it, I can send text to Slack, but for some reason the recipe causes an error. It says it's a JSON error, but I have no idea. Does anyone know the cause?

{
"request_name": "Send request",
"request": {
"method": "POST",
"content_type": "application/json",
"url": "https://hooks.slack.com/services/XXXXXXXX/XXXXXXXXXXX/AAAAAAAAAAAAAAAAAAA",
"body": "{\"text\": \"Test for sending to Slack \", \"username\": \"Grey Kitty\", \"icon_emoji\": \":sendai:\"}"
},
"response": {
"output_type": "json",
"expected_encoding": "UTF-8",
"ignore_http_errors": "false"
}
}

 Error

unexpected token at 'ok'

 Debug

The issue has been resolved.

The problem was due to setting the Response Content Type to JSON in the APP Response section.

Changing it to TEXT resulted in successful completion.
