The use of img_src AND thumbnail in the default results makes no sense (only a
thumbnail is needed). In the current state this is rather confusing, because
img_src is displayed like a thumbnail (small) and thumbnail is displayed like an
image (large).

SearXNG does not allow a None value in the content field of a result item.
If the key (shortDescription, uploaderName) in the JSON response from piped
exists but is set to None, SearXNG ignores this result item::
DEBUG searx : result: invalid content: { .., 'content': None, ..}
