Paddle-js cannot be developed and tested in the local environment

I am trying to integrate Paddle payment into the website, and I have implemented the basic payment link according to the official tutorial.
https://developer.paddle.com/build/checkout/build-overlay-checkout

But localhost:5173 keeps showing an error

[Report Only] Refused to frame 'https://sandbox-buy.paddle.com/' because an ancestor violates the following Content Security Policy directive: "frame-ancestors http://localhost".
