An error occurred during synchronization, prompting 'conditions' cannot be empty

Fei---AAA

I encountered this error when syncing my two computers. However, the strange thing is that I can see the entry information of my Zotero account on the web page, but the Zotero software still cannot sync the two devices. This is causing trouble for my work. How can I solve this problem?
