How use JSON with react-ace?

Im using react-ace and trying the readme example with java syntax. Works great. But I can't seem to set it to JSON.

Java works

import AceEditor from "react-ace";
import "ace-builds/src-noconflict/mode-java";
import "ace-builds/src-noconflict/theme-github";

<AceEditor
    mode="java"
    theme="github"
    name="UNIQUE_ID_OF_DIV"
    editorProps=
/>  

JSON does not work?

import AceEditor from "react-ace";
import "ace-builds/src-noconflict/mode-json";
import "ace-builds/src-noconflict/theme-github";

<AceEditor
    mode="json"
    theme="github"
    name="UNIQUE_ID_OF_DIV"
    editorProps=
/>  

The error

Refused to execute script from '...../worker-json.js' because its MIME type ('text/html') is not executable. (anonymous) @ 2f896707-86be-497a-93b2-e1711942d7c7:1 2f896707-86be-497a-93b2-e1711942d7c7:1 Uncaught DOMException: Failed to execute 'importScripts' on 'WorkerGlobalScope': The script at '...../worker-json.js' failed to load.
