I am doing an inner join and a GroupJoin and I have the following error

I have the following code in C# doing some inner join

public class Complaints : BaseDomainModel 
    {
        public string CaseNumber { get; set; }
        public int ClassificationId { get; set; }

    }

        public virtual ICollection<RequestAssignment> Assignments{ get; set;}
    }

GetAllById

 public IQueryable<TEntity> GetAllById(Expression<Func<TEntity, bool>> predicate, 
bool withTracking = false, bool withSplitedQuery = false)
        {
            var query = _dbset.AsQueryable().Where(predicate);

            if (withSplitedQuery) query = query.AsSplitQuery();
            else query = query.AsSingleQuery();

            if (withTracking) return query.AsTracking();

            return query.AsNoTracking();
        }

Join

var r = _unitofwork.Complaints.GetAllById(a => !a.DeletedRecord, true, true).ToList()
                 .Join(_unitofwork.IComplaintsRequeriments.GetAllById(a => !a.DeletedRecord, true, true).ToList()

                 {
                     Complaints,

I hope to bring the different join and group join of the different models
