Allow Cors Requests

The Parca server by default only allows requests from the same origin. To allow requests from other origins, you can set the --cors-allowed-origins flag to a comma separated list of origins. For example, to allow requests from http://localhost:3000, you can run the Parca server with the following flag:

--cors-allowed-origins='http://localhost:3000' or --cors-allowed-origins='*'(to allow requests from all origins).
