Can't import the named export 'useState' from non EcmaScript module (only default export is available) Can't import the named export 'useState' from non EcmaScript module (only default export is available)

I have a react functional SPFx component in VS Code and use SPFX-fast-serve.
I am trying to use react-tooltip "react-tooltip": "^5.27.0", as installed via npm
I then use that within a functional component as follows:

npm ls react-tooltip
approvals@2024.02.29 C:\Users\Guy.Martinello\Documents\repos\Approvals
├─┬ @types/react-tooltip@4.2.4
│ └── react-tooltip@5.27.0 deduped
└── react-tooltip@5.27.0

import ReactTooltip from 'react-tooltip';

<ReactTooltip
	id="RequestReasonTooltip"
	place="bottom"
	content="Hello world! I'm a Tooltip"
/>

I have also tried as follows:

import { Tooltip } from 'react-tooltip'
<Tooltip
      id="RequestReasonTooltip"
      place="bottom"
      content="Hello world! I'm a Tooltip"
  />

Can't import the named export 'useState' from non EcmaScript module (only default export is available)

Within my SPFX project, I do not see a webpack file - but do have a webpack.extend.js which I have updated as follows:

module.exports = function (buildOptions, webpackConfig) {
    // Your custom webpack configurations go here. For example:
    webpackConfig.resolve.alias = {
        "react-dom$": "react-dom/profiling",
    };

    // Add the rule for .mjs files
    webpackConfig.module.rules.push({
        test: /\.mjs$/,
        include: /node_modules/,
        type: 'javascript/auto',
    });

    return webpackConfig;
};

I have also installed react-scripts - as shown below with the rest of package.json

Any help would be much appreciated.

As you've probably seen on our troubleshooting page, the rule you added to the webpack config should fix this issue.

Best I can think of is that it's not getting applied correctly, but I'm unfamiliar with your setup to be able to say for certain. Also not sure how it being an SPFx project would break anything, never worked with it.

Also, @types/react-tooltip was for v4, so don't bother with that for v5.

Are you able to provide a sample repo that mirrors the basic configurations from your project so we can reproduce the issue?
