Error Fetching Login Data from ZKTeco Device

I always encounter this error when trying to fetch login data from my ZKTeco device.
Employee 12 exists, checks in normally, and their name ID matches their attendance ID.

Not able to figure out what is the issue ??

Can you give a proper log of that issue?

It is showing 500 status code may be server side issue.
