SigNoz Chart Update and Exporter Configuration Error

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.

I have finished updated *SigNOz* with *chart 0.14.4* and I get the following error at collectors: ```error decoding 'exporters': error reading exporters configuration for "clickhousetraces"```

``` exporters: clickhousetraces: datasource: tcp://${CLICKHOUSE_HOST}:${CLICKHOUSE_PORT}/?database=${CLICKHOUSE_TRACE_DATABASE}&username=${CLICKHOUSE_USER}&password=${CLICKHOUSE_PASSWORD}```

Why would dropping logs db resolve the error with traces exporter?
