Hey @Mrhy1996! I'm here to help you with any bugs, questions, or contribution guidance you might need. Let's figure out the issue you're facing together.

To resolve the error "unexpected character '%' in variable name" when running Dify with Docker, you need to remove or comment out the following lines from your .env file:

LOG_DATEFORMAT=%Y-%m-%d %H:%M:%S
NGINX_SSL_PROTOCOLS=TLSv1.1 TLSv1.2 TLSv1.3

This issue occurs with Docker Compose version 2.0.1 due to its inability to properly parse environment variables containing '%' characters.

To continue talking to Dosu, mention @dosu.
