E0047: unexpected characters in octal literal

Octal number literals start with 0 or 0o and can only contain digits 0 through 7 (and optionally an n to signify a BigInt). It is an error to include other digits in octal number literals:

let permissions = 0o755N;
let bcdDigits = 0o0123456789;
let million = 0o1e6;

To fix this error, fix or remove the extra digits or letters:

let permissions = 0o755n;

Alternatively, convert the octal number literal into a decimal or hexadecimal number literal:

let bcdDigits = 123456789;
let million = 1e6;
