E0032: legacy octal literal may not be BigInt

Decimal number literals can be BigInt with an n suffix. Legacy octal number literals, which start with an extra 0 digit, cannot be suffixed with n:

const ID = 012127638745381751821n;
const perms = 07750775077507750775n;

To fix this error, make the number literal a decimal number literal by removing the extra leading 0, or use the 0o to make the a modern octal literal:

const ID = 1234567890123456789n;
const perms = 0o0775_0775_0775_0775_0775n;
