The failure is reported from generate and makeRequest in /$bunfs/root/chunk-h4f48kbj.js and occurs in an Anthropic request using Opus 5. Start by reproducing the 400 with the supplied error text, then trace how advisor_tool_result and server_tool_use blocks are assembled. Done means the request is accepted without the missing-corresponding-block error.
