Most sessions eventually gets an tool_use error #8377
Description
Description
Thanks for this amazing platform!
I didn't catch a specific way to reproduce, but after some time, most of my sessions gets an error from which all prompts fail, until I fork an earlier message (but lose recent progress)
messages.161: `tool_use` ids were found without `tool_result` blocks immediately after: toolu_014DFJtopfcPpBp6EjbjZygY. Each `tool_use` block must have a corresponding `tool_result` block in the next message.
Plugins
oh my opencode
OpenCode version
1.1.18
Steps to reproduce
Just use the sessions, no specific prompts or instructions.
Happened in an existing project, and also a fresh project I started from scratch with OpenCode.
Screenshot and/or share link
When I /share there's an error "Failed to share session"
Operating System
maxOS 15.7.3
Terminal

Hard to say if ur using omo, but if possible can you share your session? Use this:
opencode export > session.json^^ Run this in your terminal do not use /export or /share for this :)
