Loki alerting send all the detected fields/labels

Hi,

I have setup loki and able to see all the logs and monitor them. There are some log patterns which i want to alert and send them to slack channel.
I’m able to send alert without any issues. The log format is json and its not sending all the detected fields/labels.
This will be more helpful to us to see the error when it comes on slack and identify it quickly instead going to Grafana and search through it again
