The console error is due to a preventive check of thumbnail existence to clean up, if any), Second time it doesn't happen because the thumbnail attribute extists (or contains NODATA).

so it's ok. It's not an error but a desired behavior (you can not avoid browser logging http errors in console). We can improve it by getting all the attributes (the entry point should always return something ) to avoid a 404, anyway this is an improvement. I'm going to sent a fix for the darken thumbnail

@tdipisa can I open new issue for this improvement?
