Error when join field has access query on virtual field

[Xmaster6y]

Describe the Bug

I have a collection Roles which is virtually linked to Projects and in relation Tenant. In the read access of Roles I query using the virtual field tenantSlug (tenant.slug).

The error happens when I list Projects, e.g. /api/projects but not when I list roles /api/roles

Maybe related to #12884
