[BUG] interface conversion: interface {} is nil, not int64 #523
Description
After about a month of collecting data it becomes impossible to load the metrics due to a 500 internal server error.
This has been a long-running issue and affects on Docker as well. I also tried building from source using commit 4b1d9dc2d3f5388440a6746c3bdce2b8e2bee91e. The only way to fix this is to nuke the InfluxDB database.
Metrics seem to be collected fine (as seen in the "last updated" field next to each disk), so the issue must be with displaying them as an error is thrown when I click a drive to view its metrics.

InfluxDB is created with:
docker run -d --restart=always -p 8086:8086 \
--network="host" \
-v /var/docker-data/influxdb2:/var/lib/influxdb2 \
--name influxdb \
influxdb:2.2I run the web dashboard in an LXC container which all my hosts send their data to.
