V5.4.2 : Alert always returns no data from InfluxDB in some graphs

I have a query that works fine to plot graph. But when i enable Alert, the condition always returns ‘No Data’. I enabled debug log in grafana and captured the InfluxDB query that is sent when Test Rule is clicked. It is as below

url=“http://x.x.x.x/query?db=mydb&epoch=s&q=SELECT+“rx-util__data”+FROM+“Cisco-IOS-XR-pmengine-oper%3Aperformance-management%2Fethernet%2Fethernet-ports%2Fethernet-port%2Fethernet-current%2Fethernet-second30%2Fsecond30-ethers%2Fsecond30-ether”+WHERE+(“Producer”+%3D+‘cvt-one-guru’+AND+“name”+%3D+‘HundredGigECtrlr0%2F0%2F0%2F2’)+AND+time+>+now()+-+1m

Same query succeeds to return output via web browser as below.

{“results”:[{“statement_id”:0,“series”:[{“name”:“Cisco-IOS-XR-pmengine-oper:performance-management/ethernet/ethernet-ports/ethernet-port/ethernet-current/ethernet-second30/second30-ethers/second30-ether”,“columns”:[“time”,“rx-util__data”],“values”:[[1590004269,“100.00”],[1590004279,“100.00”],[1590004289,“100.00”],[1590004299,“100.00”],[1590004309,“100.00”],[1590004319,“100.00”]]}]}]}

But the output from Alert page is as below
