[Question]: Try to create namespace before Shared-Data is initialized<title>

[yulink1981]

Do you need to ask a question?

• I have searched the existing question and discussions and this question is not already answered.
• I believe this is a legitimate question, not just a bug or feature request.

Thank you for your reply.

I think you are not starting the API server in a correct way. Please refer to README of API Server, install and run it with lightrag-server command. https://github.com/HKUDS/LightRAG/blob/main/lightrag/api/README.md
