API Explorer Response: Failed to fetch

Question

I’m new to REST API and the Commvault API Explorer and my first tests fail.

At first I’m creating an authorization token using the Sandbox:

Then I switch to the API Explorer and open the login (using the lock on the right hand side) and paste the token I got before:

I try to get a list of plans using the “Get List of Plans”:

I’m getting a response with an unknown response code:

In the console of Edge are two errors reporting violations of CSP directive:

The same happens using Firefox:

I was searching the web for this CSP violation, but I could not find a solution.

Is there anything I’m doing wrong? How can I get the API Explorer working?

I found the solution by myself.The Content-Security-Policy (CSP) header is a security feature that helps prevent cross-site scripting (XSS) and code injection attacks.The URL in the browser is pointing to the hostname “CS01” but in the API Explorer (swagger) you can see the Computed URL is “localhost”:For the browser the hostname “cs01” and “localhost” are not the same and therefore CSP is blocking.The solution is to use localhost in the URL:https://localhost/webconsole/sandbox/apiexplorer/

@Marc St.Check the Webserver.log. Try using POSTMAN and see if the issue is same.If Yes then raise a support case.
