Uncaught SyntaxError: Unexpected token '<'

[tunztunztunz]

Unity Version: 2020.3.26f1

I've followed all of the issue threads and tried a few different folder structures that I thought would fix the issue, but I can't seem to find what's causing this.

I'm declaring the context like this

import Unity, { UnityContext } from "react-unity-webgl";

const unityContext = new UnityContext({
  loaderUrl: "../../../../public/build/Build/build.loader.js",
  dataUrl: "../../../../public/build/Build/build.data",
  frameworkUrl: "../../../../public/build/Build/build.framework",
  codeUrl: "../../../../public/build/Build/build.wasm",
});

and I've tried

import Unity, { UnityContext } from "react-unity-webgl";

const unityContext = new UnityContext({
  loaderUrl: "../../../../public/build/build.loader.js",
  dataUrl: "../../../../public/build/build.data",
  frameworkUrl: "../../../../public/build/build.framework.js",
  codeUrl: "../../../../public/build/build.wasm",
});

and calling the player like this:

<Unity unityContext={unityContext} style={{
        height: "100%",
        width: 950,
        border: "2px solid black",
        background: "grey",
      }}/>

I see the unity player styles, but nothing loads. I've tried the following file structures (changing paths to match), but they both give me the same results.

I noticed that a lot of the documentation references a .json file that Unity no longer serves in their builds for more recent versions. Is there a different set up for 2020/2021 for this package to work?

Duplicate of #57, also explained in the documentation.

TLDR;

- loaderUrl: "../../../../public/build/Build/build.loader.js",
+ loaderUrl: "build/Build/build.loader.js",

const unityContext = new UnityContext({
  loaderUrl: "build/Build/build.loader.js",
  dataUrl: "build/Build/build.data",
  frameworkUrl: "build/Build/build.framework.js",
  codeUrl: "build/Build/build.wasm",
});

The above doesn't work and I receive the same error even though the paths are now relative to the index.html.

I've noticed two things after re-reading the documentation and the issue:

• Uncaught SyntaxError: Unexpected token '<' #57 also involves a JSON file that I do not have. How is that being handled and do I need to do anything differently for 2020/2021?
• I also noticed all of these examples don't use the index.html file that comes with the unity build unless they're using that as their index. In my case, I can't do that as the index.html file is part of my application. If this is the case, do I need to add anything there? Could two index.html files be causing this issue?

Have you tried getting the build without compression? You need to add uncompressed files while working in the React development environment.
