What's Wrong?

Invalid request
The request couldn't be completed.
API Error: 400 {"type":"error","error":{"type":"invalid_request_error","message":"messages.1154.content.2.text: cache_control cannot be set for empty text blocks"},"request_id":"req_011CbvNv1eofZXdfMSVHa5Ki"}

I am so sick of this error when I paste a screenshot in and forget to put a prompt with it. Why can you not process a screenshot why does it have to have one letter or one word with it that's the dumbest thing ever. It's a bug it needs to be fixed

What Should Happen?

i paste in a screen shot and it works without me having to have text in the same submission
