No Recent Values (and zabbix_get fails) with new template import (InfluxDB)

[me2017]

I'm having this problem with several newly imported templates...

Zabbix 6.0.12 wanting to monitor an InfluxDB 1.8. The only thing I've changed in Zabbix is {$INFLUXDB.URL}.

Here is a sampling of recent data for the template. There is only one item getting a value, two of these are failing (see red i). Is this all I should expect? What can I do to get more details?

But I'm able to succesfully run a test on more than one item:

...and yet all of these zabbix_get tests fail:
