Steps to reproduce:

Using "Gitlab by HTTP" template, zabbix 5.4

Gitlab version 13.11.4

Result:

Unsupported item with error:
Preprocessing failed for: {"status":"ok"}
1. Failed: cannot extract value from json by path "$.master_check[0].status": no data matches the specified path
Expected:
Item working the same way as liveness check is. I assume changing it to match the same data as liveness check does will resolve the issue.
