chore: fix syntax iss in the parser

[famouswizard]

Motivation

There were minor syntax issues in the code causing parsing errors:

1. A square bracket [ was left unclosed.
2. The | immediately after , is invalid syntax.

Fixing these makes the code parse correctly and prevents runtime errors.

Solution

Closed the unclosed square bracket and removed the invalid | after ,.
No functional changes beyond correcting the syntax.
