Create-react-app nginx-based deployment proxy information is overwritten

for the project created with create-react-app, proxy is configured in the package.json of the project for fetch cross-domain deployment based on nginx. After the
deployment is completed, the access page initiates a network request. The address of the request is not the information of proxy, but the domain name visited.

should be the information I configured in package.json, but it is indeed the visited domain name. Please tell me how to handle it. Thank you!
