Hey @Shubhendra Kushwaha, We're aware of the issue and have merged a fix for it.

great, thanks for the info.

Thank you for this. The helm chart at 0.88.1 appears to still have this problem, but I managed to create a patch for it. I did however, patch it such that both CLICKHOUSE_PASSWORD and SIGNOZ_TELEMETRYSTORE_CLICKHOUSE_DSN are under

env:

, as I prefer not to have the passwords in plain text.

Hey @Pedro Carvalho, @Shubhendra Kushwaha, We've released a patch version to fix the clickhouse creds: https://github.com/SigNoz/charts/releases/tag/signoz-0.88.2
