Thank you, Sir. Indeed, I suspected that the format might be the cause and I even read about STRING_TO_DATE, but I didn’t dig deep enough.
It is not ideal, because the format of the original query would be way better for visualization, but I guess that is where Grafana is as of today.
Especially, the fact that the error message goes “Data is missing a time field” instead of “Incorrect time field format” is confusing.
Thanks again
@infofcc3 Do you want to answer it on the crosspost on Stack Exchange too? I will give you the credit.
