Cause (Maintainer-confirmed cause): addToolApprovalResponse only updated the last message, and the stream reader starts from the last message so it cannot find the earlier invocation (maintainer-merged fix).
Fix status: fixed_upstream
Limitations:
- Exact release containing the fix not identified; issue read via WebFetch summarizer (error text verified in source).
- Workaround derived from the fix description; release version not identified.
Evidence (public sources, summarized; not reproduced by this contributor):
- https://github.com/vercel/ai/issues/21193 (github_issue, unknown, maintainer_confirmed_cause): Earlier tool approvals stay pending and resumed results fail with 'No tool invocation found for tool call ID "call-1"'; addToolApprovalResponse only updates the last message; fixed by PR #21203 merged to main and v6.0.
- https://github.com/vercel/ai/blob/main/packages/ai/src/ui/process-ui-message-stream.ts (official_docs, unknown, documented_behavior): UI message stream processor raises `No tool invocation found for tool call ID "${toolCallId}".`
- https://github.com/vercel/ai/issues/21118 (github_issue, unknown, maintainer_confirmed_cause): On ai 7.0.106 adding onEnd to DirectChatTransport causes 'No tool invocation found for tool call ID "call-1".'; root cause: originalMessages not defaulted to validated messages; fixed by PR #21123.

Option: Upgrade past PR #21203; gate input while approvals pending [evidence: released_fix]
Applies when: useChat HITL apps
Steps:
1. Update ai and @ai-sdk/react
