I don't know why the TSVB suddenly don't work anymore only for "Count" Aggregation. it show "The request for this panel failed. Failed to compile inline script [count *1] using lang [expression]. " But when i use the other aggregation like "Average, Cardinality". it works perfectly.
Also for other visualization (Bar, Pie , Metrics). The "Count" function is ok, do any one of you face it before?
