This issue might be a duplicate of existing issues. Please check:

  • #4254: Fatal error with JSON/syntax parsing - same "undefined is not an object (evaluating 'lines().length')" error type
  • #4178: Similar fatal error pattern after startup/config issues
  • #4246: Configuration errors preventing OpenCode from starting properly
  • #4145: Crash on bad user config with similar undefined object evaluation errors
  • #4179: OpenCode fails to launch with hanging behavior

Feel free to ignore if none of these address your specific case with prompt history JSON parse errors.

Here is the fix:
rm -rf ~/.local/state/opencode

Had to grep my entire home directory to find opencode is setting state under this directory.

Seems like a corrupted state management file caused by an unscheduled shutdown. There should be a check on the file to avoid this, before instantiating the state history?

@rekram1-node, I had the same situation as @ubuntupunk. In my case, the history got corrupted as the partition that opencode stores ~/.local/state/opencode/prompt-history.jsonl temporarily ran out of space. From that point forward, opencode just kept writing json into that history file so it was never going to fix itself. I simply deleted the offending json line, wrote the file, restarted and retained my prompt history and everything is back to normal.
