could not resolve Model using modelPaths in objectionjs and ts-jest

Question

Getting this error when running ts-jest.

Error: Member.relationMappings.primaryAssignment: modelClass: could not resolve ./MemberAssignment using modelPaths

  primaryAssignment: {
        relation: Model.HasOneRelation,
        modelClass: path.join(__dirname, 'MemberAssignment'),
        join: {
          from: 'members.primary_member_assignment_id',
          to: 'member_assignments.id',
        },
      },

Works perfectly fine when using tsc
