Invalid discovery rule value: cannot close top level object

[zxlin]

Hello,
I have migrated an old Zabbix 3.2.4 to 6.4.
In order to monitor only certain services, I have a discovery rule that uses a Powershell script to determine the services to be monitored on a server and create the corresponding items using an item prototype. I have adapted the script to the new notation.
In the list of discovery rules for a given host, I get the following message: "Invalid discovery rule value: cannot close top level object"
Unfortunately, I cannot find an explanation of what this message refers to. Is the error to be found in the return array of the script or in the configuration?

Return array:

[
    {
        "{#SERVICESTATE}": "Running",
        "{#SERVICEDISPLAY}": "Apache Tomcat 9.0 FAV2",
        "{#SERVICENAME}": "FAV2",
        "{#SERVICEDESC}": "Apache Tomcat 9.0.27 Server - https://tomcat.apache.org/",
        "{#SERVICEDIR}": "D:/apache-tomcat-9/bin/"
    },
    {
        "{#SERVICESTATE}": "Running",
        "{#SERVICEDISPLAY}": "Apache Tomcat 9.0 DA",
        "{#SERVICENAME}": "DA",
        "{#SERVICEDESC}": "Apache Tomcat 9.0.27 Server - https://tomcat.apache.org/",
        "{#SERVICEDIR}": "D:/apache-tomcat-9/bin/"
    },
    {
        "{#SERVICESTATE}": "Running",
        "{#SERVICEDISPLAY}": "Apache Tomcat 9.0 WS",
        "{#SERVICENAME}": "WS",
        "{#SERVICEDESC}": "Apache Tomcat 9.0.27 Server - https://tomcat.apache.org/",
        "{#SERVICEDIR}": "D:/apache-tomcat-9/bin/"
    }
]

My LLD configuration




What is incorrectly configured or missing in my configuration?

Bin ich hier allein oder gibt es hier keine Unterstützung?

Looks ok to me... Tried to replicate a discovery here... works OK (at least feeding your data to disco results in no errors) ..

It might be from the script ? if you call it with zabbix_get, what do you get as answer? or run locally with zabbix_agent -t ?
