 * - JSON_GET_FIELD(json_column, 0) -> json_column->0

The constant Doctrine\ORM\Query\Lexer::T_COMMA was not found. Maybe you did not declare it correctly or list all dependencies?

            $this->nodes[1] = $parser->ArithmeticPrimary();

            // If ArithmeticPrimary fails (e.g., when encountering a string), try StringPrimary
            $this->nodes[1] = $parser->StringPrimary();
