Has anyone completed a real Agent Canvas conversation with openhands/claude-opus-5-5? Which version of Agent Server did you use?

What is the problem? You can not start a conversation with opus-5.5 ? Because agent-canvas and agent-server versions are linked. But it can be that your agent-canvas connected to an old or wrong version (it is possible I think)

OpenHands sends an extra setting called prompt_cache_key when you use Claude. Its model proxy rejects that setting, so the request fails with HTTP 400 before Claude can answer. Your credentials are working. (I don't know if its something with my setup)

@millions-crayon-32880 this seems to be a problem. See the issue: github.com/OpenHands/software-agent-sdk/issues/5325 But we could eventually hot-fix it with this: github.com/OpenHands/OpenHands/issues/17706 but I don't know if it is a good idea

Cannot reproduce in SaaS but I do see prompt cache errors in local host

Yes. This is local.

@average-processor-75195 Good, thank you !

ok perfect

This one fixes it on the sdk github.com/OpenHands/software-agent-sdk/pull/5328

The findings in the agent review were incorrect?

Working on this one to address the review concerns github.com/OpenHands/software-agent-sdk/pull/5332
