TLDR Alejandro encountered an error updating SigNoz with chart 0.14.4. They resolved the issue by dropping the logs database, and Srikanth questioned the resolution's relation to the exporter error.
``` exporters: clickhousetraces: datasource: tcp://${CLICKHOUSE_HOST}:${CLICKHOUSE_PORT}/?database=${CLICKHOUSE_TRACE_DATABASE}&username=${CLICKHOUSE_USER}&password=${CLICKHOUSE_PASSWORD}```
what is wrong with that ?
```* '' has invalid keys: low_cardinal_exception_grouping 2023/05/10 18:43:03 application run finished with error: failed to get config: cannot unmarshal the configuration: 1 error(s) decoding:```
This is happend at `signoz-otel-collector`
`drop database signoz_logs on cluster cluster`
That command resolved my issue
Why would dropping logs db resolve the error with traces exporter?
