Including full log error message in alert notification using OpenSearch

Using OpenSearch plugin and trying to create an alert with the error message in the notification.
Tried a few different ways but seems OpenSearch plugin uses aggregations when defining a query for the alert rule and we don’t have access to the whole document. Checking to see if anyone figured out a way to do this.
Grafana v10.4.1
OpenSearch v 1.3.2

was able to get traction in github with a feature request now created Metric Raw Data error - input data must be a wide series but got type long · Issue #360 · grafana/opensearch-datasource · GitHub
In the meantime, does anyone know of an option to use something like promql function count_over_time like in this example with Loki
