I have flow that is receiving data from mqtt, converting such data to a json, and storing it into influxdb.
Nodered is the latest available for raspbian buster, influxdb connector (this) is of type "out", and influx is v1.8.4, listening on localhost without password and without encryption.
Unfortunately saving data to influxdb, is not working: I keep getting internal server error as response. Logs of influxdb are showing the same message reported in node-red.
Influxdb however is working well together with my Grafana.
Do you have any suggestion on how to solve the issue?
