Casl: Object prototype may only be an Object or null: undefined on no abiltity

[vemundeldegard]

I am trying to use the accessibleBy function from @casl/mongoose like this:

const matchesAbilityRights = await database
      .model("Person")
      .accessibleBy(user.ability);

My ability is defined from this JSON array:

[
  {
    action: 'read',
    subject: 'User',
    conditions: { 'organizations.organization': 5e318fb83002794738039ae2 }
  },
  { action: 'create', subject: 'User' },
  {
    subject: 'Person',
    action: 'delete',
    conditions: { creator: { '$in': [ 5d51518e5b84777cd6f54bcb ] } }
  }
]

This error is thrown when you don't have the ability. But when you do, it works like expected.

Hi

Thanks for the time to contribute this issue! The issue is fixed now and I'm currently working on another issue with types. When that is finished, I will release a patch version.

Plan to be done today, probably tomorrow
