Anthropic models do not work in the chat window #257

I tried to get claude to run but I ran into issues. It seems some of the requests went through.

 Error 19:01:44 notify.error Gp.nvim Gp.nvim: anthropic response is empty:
'{"type":"error","error":{"type":"invalid_request_error","message":"messages: Unexpected role \"system\". The Messages API accepts a top-level system parameter, not \"system\" as an input message role."}}\n'
 Error 19:01:44 notify.error Gp.nvim Gp.nvim: anthropic response is empty:
'{"type":"error","error":{"type":"invalid_request_error","message":"messages.1: all messages must have non-empty content except for the optional final assistant message"}}\n'

I explored the issue a bit further.

it seems either the test isn't being passed in or the response is empty, I also managed to overload it. What else is interesting is that it seems like every once in a while a request will go through in the chat window. the requests always go through on rewrite or 'implement'.

I can get Claude to run it with gpImplement or gpRewrite, but it is not in the chat window.

Somebody, please let me know what further details I can provide to get this issue resolved.
