I have just started to use piwebapi in R.I would like to get interpolated values every 10m with values over 200. My code below work when I leave the filterExpression out. However, when I include the filterExpression, I get the following error:
 "HTTP Status code is 502."
 "Error: [-12301] Performance Equation parsing error"
Can someone please help me to get the right syntax?
Here is my code:
piWebApiService$data$getInterpolatedValues(path = 'pi:\\\\mes\\xxxxxxxx',
startTime = '1-jul-2019',
endTime = '2-jul-2019',
interval = '10m',
filterExpression = "'value'>200")
