Fetching XML files from Azure Storage Explorer sometime fails

So for work we have a Azure Storage Explorer Fileshare where the customer sends XML files. Our Job fetches files from this fileshare every ~20 minutes maybe. Some files works fine and some just straight up fails with this code

var xmlFileByteArray = _azureHelper.GetFileBytes(fileName, sourceDirectory);

if (xmlFileByteArray is null)
{
    return;
}

var reader = new StreamReader(new MemoryStream(xmlFileByteArray));
var xmlDocument = new XmlDocument();
xmlDocument.Load(reader);

var xmlFileByteArray = _azureHelper.GetFileBytes(fileName, sourceDirectory);

if (xmlFileByteArray is null)
{
    return;
}

var reader = new StreamReader(new MemoryStream(xmlFileByteArray));
var xmlDocument = new XmlDocument();
xmlDocument.Load(reader);

And xmlDocument just says

System.Xml.XmlException: 'Data at the root level is invalid. Line 1, position 1.'

System.Xml.XmlException: 'Data at the root level is invalid. Line 1, position 1.'

The weird part is, when I locally debug it, fetch the correct file and run the same code, it doesn't fail. How could this be? They are named "123-1345.xml" or similar in the share and looks fine in notepad ++ or whatever program. Could there be some sort of "buffer" time that the file hasn't fully transformed in to a xml file yet or similar? Any help is appriciated

❔ Somewhat advanced check for ids in foreach, remove duplicated

Hi! Right now im doing somewhat of a "complex" (at least for me to understand) check of id's to remove, and wanna ask if i can do this code example simpler, or shorter, cuz it feels like i could, but cant think of how

private List<int> CheckIfIdsIsInHigher
Hierarchy(List<LowerModel> allIds, List<string> higherHierachyIds)

var idsToRemove = new List<int>();
var idsToNotRemove = new List<int>();

foreach (var highIds in higherHierachyIds)
            {
                foreach (var ids in allIds)
                {
                    if (!DoesIdExistInHigherHierachyModel(int.Parse(highId), ids.Id))
                    {
                        if (!idsToRemove.Contains(ids.Id))
                        {
                            idsToRemove.Add(ids.Id);
                        }
                    }
                    else
                    {
                        idsToNotRemove.Add(ids.Id);
                    }
                }
            }
            var result = idsToRemove.Except(idsToNotRemove).ToList();
            return result;

private List<int> CheckIfIdsIsInHigher
Hierarchy(List<LowerModel> allIds, List<string> higherHierachyIds)

var idsToRemove = new List<int>();
var idsToNotRemove = new List<int>();

foreach (var highIds in higherHierachyIds)
            {
                foreach (var ids in allIds)
                {
                    if (!DoesIdExistInHigherHierachyModel(int.Parse(highId), ids.Id))
                    {
                        if (!idsToRemove.Contains(ids.Id))
                        {
                            idsToRemove.Add(ids.Id);
                        }
                    }
                    else
                    {
                        idsToNotRemove.Add(ids.Id);
                    }
                }
            }
            var result = idsToRemove.Except(idsToNotRemove).ToList();
            return result;

Since i tried to combine

if(!DoesIdExistInHigherHierachyModel(int.Parse(highId), ids.Id) && !idsToRemove.Contains(ids.Id))

if(!DoesIdExistInHigherHierachyModel(int.Parse(highId), ids.Id) && !idsToRemove.Contains(ids.Id))

Doesnt give the same result Thanks in advance
