Error on opening a document after searching in PDM vault

SOLIDWORKS API/VBA Macros

Here’s my code snippet for getting the filepath (model + drawing) after searching the filename:

public class pdmSearch
{
    public string[] FilePath { get; }
    public string WorkflowStateName { get; }
    public bool HasDrawing { get; }

    public pdmSearch(EdmVault5 pdmVault, string variableName, string searchString, out bool found)
    {
        IEdmSearch5 pdmSearch = (IEdmSearch5)pdmVault.CreateUtility(EdmUtility.EdmUtil_Search);

        pdmSearch.FindFiles = true;
        pdmSearch.FindFolders = false;
        pdmSearch.Recursive = true;
        pdmSearch.StartFolderID = pdmVault.RootFolderID;

        if (variableName != "")
        {
            pdmSearch.AddVariable(variableName, searchString);
        }
        else
        {
            pdmSearch.FileName = "%" + searchString + "%";
        }

        IEdmSearchResult5 pdmSearchResult = pdmSearch.GetFirstResult();

        FilePath = new string[2] { "", "" };
        HasDrawing = false;

        if (pdmSearchResult != null)
        {
            WorkflowStateName = pdmSearchResult.StateName;

            while (true)
            {
                if (pdmSearchResult.Path.ToUpper().Contains("SLDASM") || pdmSearchResult.Path.ToUpper().Contains("SLDPRT"))
                {
                    FilePath[0] = pdmSearchResult.Path.ToUpper();

                    break;
                }

                pdmSearchResult = pdmSearch.GetNextResult();
            }

            pdmSearchResult = pdmSearch.GetFirstResult();

            while (pdmSearchResult != null)
            {
                if (pdmSearchResult.Path.ToUpper().Contains("SLDDRW"))
                {
                    FilePath[1] = pdmSearchResult.Path.ToUpper();

                    HasDrawing = true;

                    break;
                }

                pdmSearchResult = pdmSearch.GetNextResult();
            }

            found = true;
        }
        else { found = false; }
    }
}

Before opening the document in the Solidworks the filepath is check by File.Exists(pdmSearch.FilePath[0]) which returns false.

So I manually performed a PDM search in the windows explorer into the vault for checking the filepath and for my surprise it’s correct.

Have you ever faced similar issue?
