React Hot Loader v3. this component is not accepted by Hot Loader - reactjs

Question

I've updated react-hot-loader to v.3.0.0 and when I change something in component I get updates in the browser but I also get this warning in the console:
React Hot Loader: this component is not accepted by Hot Loader.
Please check is it extracted as a top-level class, a function or a
variable. Click below to reveal the source location:
The problem is I'm not seeing anything in the stack which would suggest me where is the error.
webpack entry
client: [
'react-hot-loader/patch',
'webpack/hot/only-dev-server',
'wicg-focus-ring',
PATHS.clientBundleEntry,
],
eslint
"plugins": [
"react-html-attrs",
"transform-runtime",
"transform-class-properties",
"styled-jsx-postcss/babel",
"react-hot-loader/babel"
]
client.jsx
function render() {
ReactDOM.render(
<AppContainer>
<Provider store={store}>
<BrowserRouter>
{app}
</BrowserRouter>
</Provider>
</AppContainer>,
document.getElementById('app'),
);
}
render();
if (module.hot) {
module.hot.accept('./app', () => { render(); });
}
EDIT:
I have changed:
export default withRouter(
connect(
(state: ReduxState) => ({
error: state.requestState.loginError,
}),
{ loginUser },
)(LoginContent),
);
into:
const withRouterLoginContent = withRouter(LoginContent);
export default connect(
(state: ReduxState) => ({
error: state.requestState.loginError,
}),
{
loginUser,
},
)(withRouterLoginContent);
... and it helped in some cases. Not sure what's the difference though.

I experienced this same problem and was able to solve it by not using "functional composition" to combine multiple higher-order-components, as described in React Hot Loader's Troubleshooting Guide.
Their "solution" at the bottom of the page fixed the warning for me. Reproduced here, it's a matter of converting:
const SuperComponent =
connect()( <-- last HoC
withSomeStuff( <-- first HoC
Component <-- a real component
)
);
To:
const WithSomeStuffComponent = withSomeStuff(Component);
const SuperComponent = connect()(WithSomeStuffComponent);
