sending uris as batch throws unexpected mimetype: text/html SOMETIMES*

[pasa13142]

Hello, first of all thanks for this amazing project!

I download images as base64 and convert them to as:

uris = ['data:image/png;base64,{}'.format(b64) for b64, _ in filtered_list]

when I send uris to server one by one as bad practice, all good. Got no error.
But when I send them to server all together. It generally throws the error below. Not on a specific one, not always, but generally. Not always part is really interesting.

You have any idea?

result = client.encode(uris, prefetch=64, batch_size=64)
