API Update Media Entry (name and description)

Hi,

We have created an Integration between Picturepark DAM and Kaltura. It is working fine except one thing. We cannot update name and description of a media entry. Updating custom metadata and the media entry itself is working fine.

I do the following:

private void UpdateMetadataToKaltura(KeyValuePair asset)
{
KalturaClient client = GetKalturaClient(KalturaSessionType.USER);
KalturaMediaEntry mediaEntry = GetKalturaMediaEntry(asset.Value.KalturaID);
string categories = GetCategoryIds(client, asset.Value);
string tags = GetStringFromList(asset.Value.Tags);

        mediaEntry.Name = asset.Value.Title;
        mediaEntry.RedirectEntryId = asset.Value.AssetId.ToString();
        mediaEntry.Description = asset.Value.Description;
        mediaEntry.CategoriesIds = categories;
        mediaEntry.Tags = tags;
        mediaEntry.SearchProviderType = KalturaSearchProviderType.KALTURA;

        client.MediaService.Update(asset.Value.KalturaID, mediaEntry);

    }

The code above throw an error the "Invalid entry schedule dates"
I don`t know what to do there, I just want to change the name and Description and would like to keep everything else like it is.

Has anyone an idea?

Thanks in advance!
Stefan
