 Javascript is not support _input grammar ?

I generate Hive.g4 (https://github.com/apache/hive/blob/master/hplsql/src/main/antlr4/org/apache/hive/hplsql/Hplsql.g4) to Javascript.

const { FileStream, CommonTokenStream, InputStream } = require("antlr4/index");

const { ParseTreeWalker } = require("antlr4/tree");

const { HplsqlLexer } = require("./parser/HplsqlLexer");

const { HplsqlListener } = require("./parser/HplsqlListener");

const { HplsqlParser } = require("./parser/HplsqlParser");

const { HplsqlVisitor } = require("./parser/HplsqlVisitor");

const { Loader } = require("./loader/loader");

const str = `select a from b;`;

const chars = new InputStream(str);

const lexer = new HplsqlLexer(chars);

const tokens = new CommonTokenStream(lexer);

const parser = new HplsqlParser(tokens);

parser.buildParseTrees = true;

const tree = parser.program();

The code throw error

internal/modules/cjs/loader.js:573

    throw err;

    ^

 This is my mistake. I have fixed it.
