a couple of question: 1- log isn’t containing any data because the query not returning any rows. However every query time, it is returning the same results as seen at the top of the image. is that expected behaviour? 2-when the query is returning a result as seen in the middle of the image, the data portion isn’t starting with “columns”{“data”.... However, on a windows machine, the data part is starting with “columns”{“data”….. why is Linux and Windows system different in this respect?
