I have a small problem with Grafana alerts notifications. I am trying to send notifications to Rocket.chat channel using Slack notification channel. I can send Test notification but I get errors when trying to send my own notifications. Problem is probably with mapping one field to proper value. In Grafana logs:
Webhook response status 400 Bad Request
Match error: Match error: Failed Match.OneOf, Match.Maybe or Match.Optional validation in field value
I tried to include message and changed units to
None in Grafana but it didn't help. I also disable image sending but still didn't help.
I saw these links:
but I can't see solution. I have only Rocket.chat WebHook, can't see its logs
