panic: runtime error: invalid memory address or nil pointer dereference #208

Closed kevinlinxc closed 1 year ago

kevinlinxc commented 1 year ago

When I try to add a Trino datasource, Grafana UI tells me "An error occurred within the plugin" and I see this stack trace in the grafana-server.exe terminal (with GF_LOG_LEVEL=debug). I removed the timestamp and logging level to make it more readable.

 level=info msg="Loading Trino data source settings"

Note that I got this error with the 1.0.2 zip but not the 1.0.0 zip
