Not Receiving Images

MacOS version: 11.7.10 (20G1427)
Bot version: ??? whatever the current one is

When I send a request for an image...

Bot acts as if "Something" is being generated....

But nothing appears.

/stats confirms no image was generated:

Apart from specifying Dall-e-3, .env is left on defaults as regards image options, I have credit on my API account and text based chat is working fine. Am I doing something wrong here, or is the /image function broken?

FOLLOWUP: I've just realised that the Bot logs errors to terminal. Here's the meat'n'potatoes:

openai.BadRequestError: Error code: 400 - {'error': {'code': 'invalid_size', 'message': 'The size is not supported by this model.', 'param': None, 'type': 'invalid_request_error'}}

I tried explicitly uncommenting the IMAGE_SIZE=1024x1024 line in .env but still got the same error. Dittot with setting any other size or with setting IMAGE_QUALITY=standard or switching to IMAGE_MODEL=dall-e-3 and using IMAGE_SIZE=512x512

I had the same issue, but it got fixed by uncommenting all image variables in env:

IMAGE_MODEL=dall-e-3
IMAGE_QUALITY=hd
IMAGE_STYLE=natural
IMAGE_SIZE=1024x1024
IMAGE_FORMAT=document
