An issue arises when attempting to log in through accounts that lack the edupersonEntitlement attribute, such as those associated with Github and Google.

I attempted to authenticate, but, the execution of the synchronize_vos function impeded my progress, resulting in the occurrence of the below error message:

Traceback (most recent call last):

    vos = self.userinfo["eduperson_entitlement"]

Exception Type: KeyError at /api/helmholtz-aai/auth/
Exception Value: 'eduperson_entitlement'

It is worth noting that no VO was defined in the HELMHOLTZ_ALLOWED_VOS list.
