Error when trying to migrate IList data type with DynamicApi.GetList

MongoDB Atlas App Services & Realm Realm
1

'm migrating data that was previously “float?” and IList<float?" to the type “string” and “IList”. I am attaching the code that performs this migration, and everything goes well when I give a DynamicApi.GetList in an IEmbeddedObject, however, when I call a DynamicApi.GetList in a “float?” gives the error “KeyNotFoundException: The given key ‘’ was not present in the dictionary”. him being the “float?” type. The error only happens when I try to call a GetList in the “MeasuredValues” field, the rest of the code works fine and performs the correct conversion. Does anyone have an idea what I might be doing wrong? See the error that appears:

See how MeasuredValues ​​is in the database, it appears in the scope as List but it is a List<float?>, I believe this is a bug in the realm, but I guarantee that in the code we are saving it as IList<float?>.

I’m attaching a drive with the old bank (the bank that tries to get “MeasuredValues”) in case it helps with anything. Link drive :

The error occurs exactly on this line:

All Code:

if (oldSchemaVersion < 2)
{
var oldOrders = migration.OldRealm.DynamicApi.All(“OrderServiceEntity”);
var newOrders = migration.NewRealm.All();

for (int i = 0; i < newOrders.Count(); i++)
{
    var oldOrder = oldOrders.ElementAt(i);
    var newOrder = newOrders.ElementAt(i);

    var oldCalibration = oldOrder.DynamicApi.Get<IEmbeddedObject>("Calibration");
    var newCalibration = newOrder.Calibration;

    if (oldCalibration != null)
    {
        for (int j = 0; j < oldCalibration.DynamicApi.GetList<IEmbeddedObject>("TablePages").Count; j++)
        {
            IEmbeddedObject oldPage = oldCalibration.DynamicApi.GetList<IEmbeddedObject>("TablePages")[j];
            var newPage = newCalibration.TablePages[j];

            for (int k = 0; k < oldPage.DynamicApi.GetList<IEmbeddedObject>("Rows").Count; k++)
            {
                UnityEngine.Debug.LogError(k);
                var oldRow = oldPage.DynamicApi.GetList<IEmbeddedObject>("Rows")[k];
                var newRow = newPage.Rows[k];

                // Convertendo o campo Nominal
                var oldNominal = oldRow.DynamicApi.Get<float?>("Nominal");
                newRow.Nominal = oldNominal.HasValue ? oldNominal.Value.ToString() : null;

                // The error is here on this line:
                IList<float?> oldMeasuredValues = oldRow.DynamicApi.GetList<float?>("MeasuredValues");

                var newMeasuredValues = new List<string?>();
                foreach (var value in oldMeasuredValues)
                {
                    newMeasuredValues.Add(value.HasValue ? value.Value.ToString() : null);
                }

                newRow.MeasuredValues.Clear();
                foreach (var newMeasured in newMeasuredValues)
                {
