The struct used by the remote load functionality uses 64 bit integers as strings.
With CH 25.8 those are no longer strings in json ClickHouse/ClickHouse#74079

graphite-clickhouse panics then.
Can maybe open a pull request in a few days to fix this.
Possible solutions would be to convert the struct to ints https://github.com/go-graphite/graphite-clickhouse/blob/master/helper/rollup/remote.go#L17-L24
or to convert the ints to strings in the select statements.
