Inconsistent AI_TypeValidationError when submitting requests #5031
Description
Description
This is my first time using OpenCode so apologies if I'm not clear as I am still learning how to use it.
Immediately after I set up Zen, I selected Grok Code Fast 1, I ran /init in planning mode on my empty project and got this:
AI_TypeValidationError: Type validation failed: Value: {"code":"Some resource has been exhausted","error":"Channel xcode-0828-joint-klfix-lap7-unified-zpw7m-0 is overloaded: load=599414, num_requests=11"}.
Error message: [{"code":"invalid_union","errors":[[{"expected":"array","code":"invalid_type","path":["choices"],"message":"Invalid input: expected array, received undefined"}],[{"expected":"object","code":"invalid_type","path":["error"],"message":"Invalid input: expected object, received string"}]],"path":[],"message":"Invalid input"}]I ignored it, and continued to plan with no issues.
After I switched to build mode, it worked well until it seemed to have finished.
AI_TypeValidationError: Type validation failed: Value: {"code":"Some resource has been exhausted","error":"Channel xcode-0828-joint-klfix-lap7-unified-cnwmr-0 is overloaded: load=944000, num_requests=11"}.

This is grok having scaling issues, this morning I merged a fix so that we will properly retry it, they arent sending error status codes tehy are sending a 200 but then streaming this error chunk.
So i merged some logic to handle that, itll be in the next release

@rekram1-node Sweet, thank you! Could you possibly link the PR so I can take a look if its not too much trouble?
