[harshav167]

Summary

TUI crashes with "[Reconciler] Unknown component type: spinner" during prompt render.

Steps to reproduce

1. Build OpenCode locally from branch feature/session-directory-filtering (HEAD 4bbb0df, based on dev bded900ef).
2. Run the built binary (oc-custom / opencode).
3. TUI crashes on startup.

Actual

Expected

TUI should render without crashing.

Environment

• macOS 26.3 (25D5087f), arm64
• Bun 1.3.5
• package version: 1.1.8
• @opentui/solid 0.1.70 in bun.lock (stack trace shows @opentui/[email protected] path)
• @opentui/core 0.1.70
• opentui-spinner 0.0.6
• Branch: feature/session-directory-filtering
• HEAD: 4bbb0df835a83d195314694f4fc1cb7ea0d271f0
• Base dev: bded900ef7de536faaa791aeffbcbbf727a98432

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

• #7061: opentui: fatal: Anchor does not exist - Another @opentui/solid reconciler error with very similar stack trace pattern (reconcileArrays → insertExpression → createRenderEffect)
• #4606: TUI Crashes - TUI crash after component rendering with similar reconciliation failure
• #3749: TUI crashes during prompt edit - Related crash in prompt/index.tsx (the same file mentioned in your stack trace)
• #7392: opentui: fatal: answer.join is not a function - Another component type error during rendering
• #1220: Opencode crashes the entire terminal session right after open - TUI startup crash issue

The root cause appears to be related to @opentui/solid component registration or version incompatibility. Note that your stack trace shows @opentui/[email protected] but bun.lock lists 0.1.70 - this version mismatch may be significant.

Feel free to ignore if your specific case differs from these issues.
