侧边对话隔离检查失败

Error message

侧边对话隔离检查失败

What it means

After creating the side conversation, the remember callback validates that the returned conversation is a genuinely isolated ephemeral side task: it must exist, must not be the parent threadId, must have sideConversation===true and ephemeral===true. If any check fails the library throws, because proceeding would mix organizer output into the main thread.

Solutions

  1. Update the Codex host to a version where thread/start with sideConversation creates an ephemeral side task.
  2. Check manager.getConversation(sideId) output in the console to see which isolation flag is missing and report/patch accordingly.
  3. Update conversation-canvas to a build matching your Codex version's side-conversation semantics.
  4. Retry creation — if the conversation was briefly unavailable in the manager, a fresh attempt may pass the check.

Example fix

// before
if(!sideId||sideId===threadId||side?.sideConversation!==true||side?.ephemeral!==true)throw Error('侧边对话隔离检查失败');
// after
if(!sideId||sideId===threadId||side?.sideConversation!==true||side?.ephemeral!==true){console.warn('isolation check failed',{sideId,threadId,side});throw Error('侧边对话隔离检查失败');}
Defensive patterns

Strategy: validation

Validate before calling

const side=manager.getConversation(candidateId);if(!candidateId||candidateId===threadId||side?.sideConversation!==true||side?.ephemeral!==true){/* recreate or abort */}

Type guard

const isIsolatedSide=(c,threadId)=>!!c&&c.sideConversation===true&&c.ephemeral===true;

Try / catch

try{await nativeSideChat(...);}catch(e){if(String(e.message).includes('隔离检查失败')){resetSession(session,save);return nativeSideChat(...);}throw e;}

Prevention

When it happens

Trigger: native.Q1 returns a conversationId that is falsy, equals the parent threadId, or whose stored conversation lacks sideConversation===true or ephemeral===true — e.g. the host forked full parent history into a normal conversation instead of creating an ephemeral side task.

Common situations: A Codex version whose composer callback forks parent history instead of creating a side task (the comment in the source notes this failure mode); the conversation was evicted from the manager before the check; a host regression returning the parent thread as the new conversation id.
