If you’re a web developer, it’s important to ensure that your application works in all web browsers, including Opera. The browser is based on a Chromium engine, so it’s quite similar to Chrome in terms of functionality.

Opera offers a wide array of features, it supports Chrome extensions, and if you haven’t tried it, we suggest that you do so.


Opera is a powerful Chromium browser, intended for both developers and average users alike.

What do I do if the Field browser doesn’t contain a valid alias?

In this article

1. Check import paths

  1. Check your Webpack configuration.
  2. Locate the following line: import DoISuportIt from 'components/DoISuportIt';
  3. Change it to: import DoISuportIt from './components/DoISuportIt';

After making these changes, check if the problem is resolved.

2. Check the entry resolve values

  1. Open your configuration file.
  2. Locate the entry value and make sure that the path is correct. Usually, the problems occur due to missing ./ at the beginning of the file name.
  3. Now check the resolve value and make sure that it’s included.

This solution worked for React projects, so feel free to try it out.

3. Check the casing

  1. Open the configuration file.
  2. Locate the following line: ./path/pathCoordinate/pathCoordinateForm.component
  3. Change it to: ./path/pathcoordinate/pathCoordinateForm.component

This is just one instance of the issue, and it might not work for everyone, so be sure to check the casing on your file paths.

4. Check your aliases

  1. Open your configuration file.
  2. Now locate your aliases and inspect them thoroughly.
  3. Make sure that they aren’t using any names that are already taken.

Users reported Field browser doesn’t contain a valid alias configuration because they used redux as an alias, but after changing it to something else, the issue was resolved.

5. Check for any typos

  1. Open the webpack.config.js file.
  2. Look for any typos, especially related to commands.
  3. Also, make sure that the export command is present.
  4. If not, simply add the following code and save changes to fix that: export default Config;

Several users reported that they used export instead of exports, and that led to this problem. The issue can also appear if you don’t have the export command at the end of the config file.

This error occurs if Webpack isn’t configured properly or if your paths aren’t correct, but after adjusting that, the issue should be gone.
