When my project is packaged into the subnet, an error message appears

```
{
key: "covariant",
value: function(A) {
-> var t = Math.pow(BigInt(2), BigInt(this._bits-1)) * BigInt(-1)
->, e = Math.pow(BigInt(2), BigInt(this._bits-1))-BigInt(1);
if ("bigint" === typeof A)
return A >= t && A <= e;
if (Number.isInteger(A)) {
var n = BigInt(A);
return n >= t && n <= e
}
return !1
}
```

Uncaught (in promise) TypeError: Cannot convert a BigInt value to a number

I think when using Math, BigInt format should not be passed in as a parameter
