I try to make Query variable at grafana v. 8.0.2, and 8.0.4 very simple
select CAST(ex_name as TEXT) q1 from history_model3 group by ex_name;
but every time get error “Validation: Cannot read property fields of undefined. Templating: Error updating options Cannot read property fields of undefined”
Select return 4 values
AMEX
MOEX
NASDAQ
NYSE
that’s all, I’ve made CAST? but without any results
I’ve using data source Sqlite DB plugin
I don’t understand what the reason of this error
sorry cant help
I havent used sqlite
tried asking you for table structure (field name / values) → which we might work it from there
but if you said it is a bug, then we stop trying
