Hey @mayiming0708! I'm here to help you with any bugs, questions, or contributions you have for the project. Let's tackle this together!

It seems like you're encountering a ValidationError related to the LOG_TZ configuration in the DifyConfig class. The error indicates that the LOG_TZ field is expected to have at least one character, but it appears to be an empty string.

The LOG_TZ configuration is used to set the timezone for log timestamps, and it should be a valid timezone name according to the IANA Time Zone Database, such as 'America/New_York' ^[1][2].

To resolve this issue, ensure that the LOG_TZ field in your configuration is set to a valid timezone string. If you don't need to specify a timezone, you can set it to None, which will use the system's default timezone.

If the issue persists after setting a valid timezone, it might be related to changes introduced in the commit bab5c542197f935d35fe75eb5d2c3301fbbf58b4. Unfortunately, I don't have specific details on what changes were made in that commit, but reverting it seems to resolve the issue according to your description. You might want to review the changes in that commit to understand how it affects the LOG_TZ validation.
