I also have this kind of BUG when are they going to fix it?

alexsohr · 8 months ago

I’m running multiple sub-agents in parallel. If any one of them fails with this error, the entire process becomes unrecoverable. I'm not aware of any mechanism to retry, isolate, or recover from the failure.
Please help.

Had that too, as a workaround I used /resume and restored one message behind of (current) to recover from the infinite Run /compact to compact & continue bug
