Describe the bug

I don't know what the bug is.

I was in a conversation on restyling a simple component, and I attached a JPEG for visual guidance. Warp was 'warping' the request and then got the bad request response. Now, EVERY prompt I enter cannot be processed as they all result in Bad Request

To reproduce

Not sure how I got into that state, and now:

1. Type ANY prompt
2. Warp fails regardless of whether an image is attached or not

Here's the latest conversation ID: {"conversation_id":"4f914d91-abfd-4a12-b952-f3b7c29aa0af"}

Expected behavior

I expected Warp to begin working through tasks designed to restyle code underlying a simple hero component.

No

Yes, I confirmed that this only happens in Warp, not other terminals.

I was hoping to try this tool out as well. I am getting a similar error:

I'm sorry, I couldn't complete that request.

@daveelux This seperate error is being tracked here: #7679

We need a bit more information before we can continue triaging this issue.

If you're still hitting this, could you try reproducing it on the latest version of Warp and share logs along with a screenshot or short video if possible?

If there's no activity after 3 business days, we'll close this out to help keep the tracker tidy.

Same here. Get this error: I'm sorry, I couldn't complete that request.

Response stream finished unexpectedly with internal error: Anthropic API error: POST "https://api.anthropic.com/v1/messages?beta=true": 400 Bad Request (Request-ID: req_011CcYCY6i29tXG4jSSr2XpK) {"type":"error","error":{"type":"invalid_request_error","message":"messages.4.content.3.image.source.base64.data: At least one of the image dimensions exceed max allowed size for many-image requests: 2000 pixels"},"request_id":"req_011CcYCY6i29tXG4jSSr2XpK"}

Then the only solution is to copy thread and start a new terminal and share it and have Warp go through all the work that was done before. And, of course, inevitably, it will crash again. Rinse and Repeat.
