These types of errors can prevent your web apps from working properly. But luckily there’s a way to fix this problem, and in this article, we’re going to show you how to do it. But first, let’s have a quick look at the possible scenarios involving this error. Here’s what readers worldwide reported:

Quick tip: 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.
How can I fix the Field browser doesn’t contain a valid alias?
1. Check import paths
After making these changes, check if the problem is resolved.
2. Check the entry resolve values
This solution worked for React projects, so feel free to try it out.
3. Check the casing
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
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
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.
