From 5bc8920aaa22c5d21c21039c9e7b112b8fb2bf5b Mon Sep 17 00:00:00 2001 From: Codeplane Agent Date: Sun, 31 May 2026 17:43:09 +0000 Subject: [PATCH 1/2] fix(tui): stop session-switch crash from object-valued tool fields in MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The TUI crashed with a fatal "TextNodeRenderable only accepts strings, TextNodeRenderable instances, or StyledText instances" when switching into a session whose parts contained tool input/metadata or diagnostic/error fields that were not strings. Root cause: `packages/codeplane/src/tui/routes/session/index.tsx` interpolated several `unknown`/`any`-typed values (tool `state.input.{command,pattern,url, query,name}`, `diagnostic.message`, and `message.error.data.message`) directly as children of opentui `` elements. Those fields can hold partially streamed or model-supplied objects/arrays. On session switch, `syncSessionData` in `context/sync.tsx` reloads all messages/parts and SolidJS re-renders them; an object child reaches opentui's `TextNodeRenderable.add()`, which only accepts strings/StyledText and throws, taking down the whole TUI. It reproduced with and without a PDF attachment because the trigger is the tool/diagnostic render path, not attachments. Fix: add `textValue()` (new `src/tui/util/text-value.ts`) that always returns a string — passing strings through, rendering nullish as "", coercing scalars, and JSON-serializing objects/arrays with a defensive fallback — and wrap every at-risk `` interpolation with it. This mirrors the existing guards in `feature-plugins/system/session-v2.tsx` and `routes/session/permission.tsx`.
