Undefined object from an ajax request

Hi all,
I am actually retrieving data from my influxdb database and I have the following result. It says also that it is undefined.

How can I select the infos in series please ? Did anyone has this before ?

Thank you in advance.

Hi @Caro
It looks to me like the data is being returned in the series: Array[0] object but it’s hard to tell without more details.
