Hello,
I have enabled webhooks on my mattermost instance and configured notifications on gitlab but it returns the error :
HTTP 400 {"id":"web.incoming_webhook.text.app_error","message":"Aucun texte indiqué","detailed_error":"","request_id":"x","status_code":400}
Mattermost log :

Gitlab version : gitlab.com
Mattermost version : 6.1.0 free edition
I have other incoming webhooks on my mattermost instance that work
