Preprocessing javascript base64 text

[e_merb]

hi all
i want to decode base64 encoded text that i sent from zabbix_sender but when in Preprocessing step i return atob(value) i got [object Uint8Array]
i test with this custom script and just got same result

try {
    b64 = btoa("utf8 string");
    utf8 = atob(b64);
    return utf8;
}
catch (error) {
    return {'error.name' : error.name, 'error.message' : error.message}
}

how can i decode base64 text in zabbix

hi
read this: https://www.zabbix.com/documentation...on/whatsnew701

The JavaScript function atob now returns an array of 8-bit unsigned integers instead of a decoded string.

and try this code for preprocessing:

var arr = atob(value);
const decoder = new TextDecoder();
const str = decoder.decode(arr);
return str
