CORS

Occasionally there is an error with the Corso. How to fix?

Front on react, back on nestjs(express). Corsa is unlocked, but occasionally an error occurs when sending audio to the back:
"has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource."
If you run the application on the localhost, no errors occur, only in the prod (on aws).
