Uncaught (in promise) LoadJS

[Swapnilchavan18]

loadjs(['https://test.com/js/fuploader.js'], 'photouploader');

while trying to load java-script file, I am getting error on single page react application.

What's the error you're getting? Also, which OS/Browser are you using?

I am using chrome/windows 10, file loads on first load but when navigated back to same route where I am loading file, I get error "Uncaught (in promise) LoadJS" and js file does not load. I think it happens because file has to load from cache.

Can you share code to re-create the error on JSFiddle or CodePen? By "navigating back" do you mean hitting the back button?

[Swapnilchavan18]

Its single page application , I mean without refresh.

Can you share code to reproduce the error? Does the fuploader.js file matter or are you getting the same error with other files?

I need more information to be able to debug the problem or recommend a work-around.

Is there anything that I have to do in componentWillUnmount to load files when there is not a refresh between pages i.e for single page app

Based on your description I can't make any recommendations. If you can share some example code I can help you diagnose the problem. Can you paste the code into GitHub?

got the same exact error when loading js files on componentWillMount, it works the first time the component mounts after remounting again , it throws Uncaught (in promise) LoadJS --- asyncToGenerator.js:6 in the console. the asyncToGenerator.js :

  try {
    var info = gen[key](arg);
    var value = info.value;
  } catch (error) {
    reject(error); // error is thrown by this 
    return;
  }

  if (info.done) {
    resolve(value);
  } else {
    Promise.resolve(value).then(_next, _throw);
  }
}

@Sharl212 Thanks for letting us know. Can you share some example code that reproduces the problem?

@Sharl212 @Swapnilchavan18 Based on your description of the problem I think the issue might be that each call to componentWillMount() defines a LoadJS bundle but LoadJS throws an error when you try to reuse a previously used bundle name. Here's an example that highlights this condition: https://jsfiddle.net/muicss/2d9ryjfp/

In your code, are you defining a bundle name when you call loadjs()?
