I'm using Analytics v2 since few months with quite good results.
I periodically executing a similar command to the following one.
My goal is to extract detailed info about visits, use and so on.
Until the 15th of August , everything was ok but after that date I'm experiencing the following error at each call:
Invalid field header specified: "..." The field either does not exist or may not exist within the time range specified.
Playing a little with the fields parameter, every configuration doesn't work for me.
As an example:
The following command succeed (note the period is 2017-07-20T00:00:00 to 2017-07-20T10:00:00).
The following command fails (note the period is 2017-08-20T00:00:00 to 2017-08-20T10:00:00).
Thank you in advance for the support.
