<?php
    public function build(LexerInterface $lexer, array $params): ?array
    {
        $parseFunction = function (LexerInterface $lexer): array {
            return $this->buildAST(ASTKindEnum::INPUT_VALUE_DEFINITION, $lexer);

The expression return $this->buildAST(Digia\GraphQL\Language\ASTBuilder\ASTKindEnum::INPUT_VALUE_DEFINITION, $lexer) could return the type null which is incompatible with the type-hinted return array. Consider adding an additional type-check to rule them out.

        };

        return $this->peek($lexer, TokenKindEnum::PAREN_L)
            ? $this->many(
                $lexer,
                TokenKindEnum::PAREN_L,
