Error towards To check

Hi everyone,
Can someone tell me how to avoid this error and go To check?
Error

you have to find what cause this issue and prevent it using something like that:

if (*crash cause*)
{
	data.STATUS = "BAN";
	return;
}

OR

try {
	*your code here*
}
catch {
	data.STATUS = "BAN";
	return;
}

you could replace BAN by RETRY depending on what you want

I don’t know what you mean by the codes (* crash cause*) and * your code here* .And if it goes between *
