GitHub user mosescha1972 created a discussion: Inquiry Regarding 400 Error When
Sending Superset Alert to Mattermost Incoming Webhook
Hello,
I am trying to send alert information from Apache Superset to a Mattermost
Incoming Webhook as plain text. However, I am encountering the following error
message:
Webhook failed with status code 400:
{"id":"web.incoming_webhook.text.app_error","message":"지정된 텍스트가
없습니다.","detailed_error":"","request_id":"xoz1q6iby7fm7ebgngbnwusy4w","status_code":400}
It appears that the webhook request is being rejected because no text field is
detected in the payload.
Could you please advise on the correct payload format required by Mattermost
when sending text-based alerts from Superset? Specifically:
Is the "text" field mandatory in the JSON body?
Are there any additional required headers or formatting rules?
Does Superset require any specific configuration to properly send the text
field?
Thank you for your assistance.
