Hey, thanks for the detailed report with the Request ID. This is a known bug on our side. When a chat context grows far beyond the model’s token limit, auto summarization can’t shrink it fast enough, and the step gets stuck retrying until it fails with Failed to run step, exceeded max retries. That’s why even “hello” won’t go through. It’s the existing oversized chat that’s failing, not your new message. This shows up more often on Auto or Composer than on Sonnet.
What helps right now:
- Start a new chat. This specific broken thread can’t be recovered, and new messages in it will keep failing.
- For heavy chats, pick a specific model instead of Auto.
- If possible, don’t paste or generate huge tool outputs in a single chat.
We’re tracking the issue, but I can’t share an exact ETA for a fix yet. I’ll post an update in the thread if I have one. There’s also a discussion of the same error here: Internal Error: An unexpected error occurred on our servers. Please try again, or contact support if the issue persists
