Error resuming chat
Failed to resume after background task completed: Al Model Not Found Model name is not valid:
“eu.anthropic.claude-opus-4-6-v1” Request ID: 36a4ca44-cf71-4880-a628-0775b7dc2a30
it makes it really hard to work
Steps to Reproduce
Enable AWS bedrock and spawn any background agent → it fails once it finishes
Hey, thanks for the report with the request ID and version. This is a known bug. When resuming a sub-agent after a background task on BYOK AWS Bedrock, Cursor sends the raw Bedrock model ID like eu.anthropic.claude-opus-4-6-v1, and the backend rejects it because validation only allows names from the Cursor catalog.
We’re already tracking this bug. I can’t share an exact ETA for a fix yet. Once we have an update, we’ll post it in this thread.
Unfortunately, there isn’t a clean workaround right now. The BYOK Bedrock model picker only shows Bedrock names, and the catalog names won’t work when BYOK is enabled. If you can temporarily work without sub-agents, the normal single-agent flow on the same Bedrock model should work fine, and that’s the fastest way to avoid this error for now.
If you hit any other symptoms, please share new request IDs here. It really helps with debugging.
Hey, unfortunately I can’t share an exact ETA yet. The bug is being tracked and is a high priority, but I don’t have a specific fix date. As soon as I have an update, I’ll reply in this thread.
I get that the workaround with a single agent and no sub-agents isn’t a real replacement, but for now it’s the most reliable way to get around the issue on BYOK Bedrock.
