Receiving the message: "401 - Not authenticated" to the logged-in agent #152

Hello, I developed an API that accesses resources on my pod. Access to resources requires the user to authenticate. The user authenticates to a web application that consumes the API. The application uses the solid auth client. After authentication, the API is called and the resources are read from the pod and returned to the user. However, it only works if access is granted to the general public (acl:agentClass foaf:Agent). When I grant access to an individual agent (acl:agent https://jleles.solid.community/profile/card#me), I receive the following message: "401 - Unauthenticated".
How to solve this? Thanks to anyone who can help!

.acl

<#authorization>
    a acl:Authorization;
   acl:agent <https://jleles.solid.community/profile/card#me>;
    acl:accessTo <./file1.owl>;
    acl:default <./>;
    acl:mode acl:Read.
