CORS issue calling to railway from other domain

Project ID : b1d6fa08-43ff-4114-82f0-f836e0ee2651 Hi, I'm getting this error when trying to call from my frontend to Flask backend server hosted on Railway:


Access to fetch at 'http://c...pp/1980' from origin 'http://localhost:3000' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: Redirect is not allowed for a preflight request.

Here is my flask server looks like:

 ------------------ SETUP ------------------
load_dotenv()
app = Flask(__name__)
# this will need to be reconfigured before taking the app to production
cors = CORS(app, resources={r"/*": {"origins": ["http://localhost", "http://localhost:3000", "http://c...pp"]}})
...
# ------------------ START SERVER ------------------

if __name__ == '__main__':
    app.run(debug=True, port=os.getenv("PORT", default=5000))

Do you have any suggestion? Anyway, thank you for building amazing railway!

Can not render react component inside Overlay

I am trying to render a component from deepchat.dev in the overlay to make a floating chat box, but it ends up showing no overlay at all. I tried to render the component alone, inside the span,... but it didn't work and inspecting shows no CSUI has been rendered. However, when I remove the <DeepChat> component, the span is rendered fine. The <DeepChat> component works perfectly fine in the pop-up, the bug happens only on CSUI Anyone encountered this before?

const PlasmoOverlay = () => {
  return (
    <span
      className="hw-top">
      CSUI OVERLAY FIXED POSITION
      <DeepChat
        demo={true}
        style={{ borderRadius: '10px' }}
        textInput={{ placeholder: { text: 'Welcome to the demo!' } }}
        initialMessages={initialMessages}
      />
      <h1>Deep Chat</h1>
      
    </span>
  )
}
