I save a file on a folder on SharePoint Online. After saved it, I tried to update metadata informations. But I receive an abnormal error.
{HttpResponseCode: 400Code: System.ArgumentExceptionMessage: Column 'FieldName' does not exist. It may have been deleted by another user.
Code:
IFile filesavedonfolder= await myfolder.Files.AddAsync(myfilename, mystreamcontentfile, false);
await filesavedonfolder.ListItemAllFields.LoadAsync(x=> x.All);
var itmLista = filesavedonfolder.ListItemAllFields.ParentList.GetAsync();
filesavedonfolder.ListItemAllFields.Values.Add("FieldAdded", "Some text value");
await filesavedonfolder.ListItemAllFields.UpdateAsync();
////////////////////////////////////////////////////////////////////////////////////////////////
When I executed UpdateAsync, I receive this error
{HttpResponseCode: 400Code: System.ArgumentExceptionMessage: Column 'FieldAdded' does not exist. It may have been deleted by another user.
Do you know why and how I can solve it?
Thanks a lot
S
