When I run my vxml application I get this syntax error - ecmascript-5

Question

I get this error when I run my vxml app;
"ECMAScript runtime error: Compilation produced 1 syntax
errors.\n\nWhile evaluating:\n\"var acc_no = [37492414, 94190610,
23228367, 39574988, 64742440];\n\t\t\t\t\tfunction checkAccount(arr,
val) {\n\t\t\t\t\treturn arr.some(arrVal => val ===
arrVal);\n\t\t\t\t\t\t\t\t\t\t\t} \"";
Here's my vxml script where the error arises:

I am still new to vxml and ecmascript.

Answer 1

The ECMAScript in question seems to be syntactically correct:
var acc_no = [37492414, 94190610, 23228367, 39574988, 64742440];
function checkAccount(arr, val) {
return arr.some(arrVal => val === arrVal);
}
I would suggest breaking this piecemeal and reduce the complexity of the VXML code to debug it. Use a very basic VXML file with one simple field, put the above ECMAScript in the filled section and then see if you get the same error. If you do, move the script further up in the code (i.e not in the filled section) and again check if you get the same error.
The error statement is a bit confusing because of the linefeeds etc. Does the error message look like that when you see it the first time?
