webpack-dev-server proxy not working - reactjs

Question

My app uses a Python backend so when I'm running locally I need to proxy my requests to a different port than what Webpack is running on.
I've tried several different ways of making this work:
devServer: {
contentBase: outDir,
proxy: [
{
path: "**",
target: "http://localhost:8000",
secure: false,
bypass: function(req, res, options) {
if(req.url === '' || req.url === '/') {
res.statusCode = 302;
res.setHeader('Location', '/a/');
return '/a/';
}
var frontend = new RegExp("^\/$^|\/a\/index\.html|^\/a\/|^\/a$|^\/styleguide");
if (frontend.test(req.url)) return req.url;
}
}
],
// serve index.html for all 404 (required for push-state)
historyApiFallback: true,
},
And this:
proxy: [{
context: '/',
target: 'http://localhost:8000',
}],
Both of those will at least show a message similar to this when it starts up: [HPM] Proxy created: ** -> http://localhost:8000. When I look at the docs and do something like this, it doesn't work either (I don't even get a message about the proxy running):
proxy: {
"/": "http://localhost:8000"
}
Is there something obvious I'm doing wrong? I'be been trying every combination that I can think of to make it work.

Try to add changeOrigin: true. Don't forget to change API pattern.
proxy: {
'/api/**': {
target: 'http://localhost:8000',
secure: false,
changeOrigin: true
},
}
