The most likely cause for this issue is A. The application ID or Application Provider does not have the correct permissions on the safe. The CyberArk Central Credential Provider (CCP) is a web service that enables applications to retrieve secrets from the CyberArk Vault using REST API calls. The CCP requires an application ID or an Application Provider to authenticate and authorize the application before returning the requested secret. The application ID or Application Provider must have the Retrieve and List permissions on the safe where the secret is stored, otherwise the CCP will not be able to find the matching secret and will return an error.

To resolve this issue, you should verify that the application ID or Application Provider has the correct permissions on the safe, and that the safe name and object name are correctly specified in the REST API call. You can use the CyberArk Privileged Access Security Web Access (PVWA) or the PrivateArk Client to check and modify the permissions on the safe. You can also use the CyberArk REST API Tester or a tool like Postman to test the REST API call and see the response from the CCP. For more information, refer to the following resources:
