This issue is a known bug in Dify version 1.1.0 when using Hybrid Search with Weighted Score. The error "Cannot read properties of null (reading 'vector_setting')" is a confirmed issue, and the development team is aware of it. They plan to release a hotfix version to the cloud within hours and new Docker images in the following week. Unfortunately, there is no immediate workaround available, so users will need to wait for the updated version to resolve the issue ^[1][2].
