@lleo126 Hello, why should you empty the link configuration?

@gqcn Due to #4058, note.link = "" was accidentally deleted, causing the database connection configured in link mode to fail.

gf v2.8.3 其中 note.link = "" 被误删，导致走到configNodeToSource的已废弃分支，致使link方式配置的数据库连接失效

目前看link配置项是生效的，有复现代码吗？或者提交对应单测验证一下呢？
