UnityContext is not a constructor.

[michaelcuneo]

Describe the bug

Using the sample code, with the name of my Unity project changed, I get

Uncaught (in promise) TypeError: react_unity_webgl__WEBPACK_IMPORTED_MODULE_3__.UnityContext is not a constructor.

Maybe there is something wrong compiler settings, what are you using? Babel, Typescript?

See source: unityContext.ts

  /**
   * Creates a new instance of the Unity context model.
   * @param {IUnityConfig} unityConfig The Unity config used to build the player.
   */
  constructor(public unityConfig: IUnityConfig) {
    if (typeof (window as any).ReactUnityWebGL === "undefined")
      (window as any).ReactUnityWebGL = {};
  }

Babel, I am running on top of Max-Stoibers, react-boilerplate. 4.0.0

[michaelcuneo]

Oh, I need TypeScript for this?

[jeffreylanters]

No, it's both JavaScript and TypeScript compatible. I assume there is a problem with your compiler settings. I recommend taking a look at the test repository.

Compiler Settings of the Unity project?

Same error with the react-unity-webgl-test ... https://haldor.michaelcuneo.com.au/errors.PNG

[michaelcuneo]

All I did to make this error was git clone the react-unity-webgl-test rename the include in react-unity-webgl-test for the react-unity-webg so that the import points to an actual import instead of a .tgz. run npm install. Then run npm start.

http://haldor.michaelcuneo.com.au:3001/ ... this is it running live, straight from the cloned code, with zero changes.

It turns out that this dev environment doesn't function to find the files, so it gave these errors, if I run npm run build, I can see a Unity project in my window, with the test version, rb 4.0.0 won't allow me to see the files in dev, so I must run npm run build first, then look, now that it does find the files, it has different errors.

I'm getting same error: UnityContext is not a constructor even after npm run build. I'm using React.version 16.13.1.

@michaelcuneo You've probably entered the wrong URL's to the Unity Context model. Can you check your network settings to see if these files are loaded correctly?

@motiondirector Are you sure you've imported the class correctly? Can you console.log(typeof UnityContext) to verify this.

@jeffreylanters Thanks! I'm using ^7.1.10 version with Unity 2019 WebGL build. Resolved by using UnityContent instead of UnityContext.
