How to build Linq Query setp by step to retrieve data from DBSet

Question

I am building a dynamic query with some predicates, some may be a .Contains(), others a .StartsWith(), ...

But when I try to retrieve the entities I get a weird EF Core error:

System.InvalidOperationException: 'The LINQ expression 'DbSet() .Where(t => Invoke(__predicate_0, t.EndsOn) )' could not be translated. Either rewrite the query in a form that can be translated, or switch to client evaluation explicitly by inserting a call to 'AsEnumerable', 'AsAsyncEnumerable', 'ToList', or 'ToListAsync'. See https://go.microsoft.com/fwlink/?linkid=2101038 for more information.'

IQueryable<Api.Data.Models.Travel> query = _travelContext.Travels.AsQueryable();

foreach(var predicate in travelQuery.Predicates.StartDate)
    {
        query = query.Where(travel => predicate(travel.StartedOn));
    }

foreach (var predicate in travelQuery.Predicates.EndDate)
    {
        query = query.Where(travel => predicate(travel.EndsOn));
    }
var x = await query.ToListAsync();
Console.WriteLine(x);
