GuidSerializer changes

 GuidSerializer cannot serialize a Guid when GuidRepresentation is Unspecified" indicates that the MongoDB C# driver is encountering a GUID (Globally Unique Identifier) that does not have a specified representation during serialization.

This typically happens when the driver needs to know how to store the GUID in MongoDB, but the default or configured GuidRepresentation is Unspecified.

Resolution Steps:

  BsonSerializer.RegisterSerializer(new GuidSerializer(GuidRepresentation.Standard));

  if (customer.CustomerGuid== Guid.Empty)
  {
      customer.CustomerGuid = Guid.NewGuid();
  }

  customer.CustomerGuid = Guid.NewGuid();

  await this._customerService.UpdateCustomerAsync(customer);

  _workContext.CurrentCustomer = customer;
