Please pull from dify main branch and reset the docker compose if you modified it. Issue has been fixed.

Hi guys,

Check this link: https://github.com/langgenius/dify-plugin-daemon/blob/main/.env.example

Here you will find the environment variable, and set:
DB_SSL_MODE: "require"

This worked for me.
Cheers.
