Tool Result Block Missing in Async Promise Handling

[tim-watcha]

Bug Description I got this message: This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). The promise rejected with the reason: McpError: MCP error -32603: Tool not found: closeAllDiffTabs at Mc1._onresponse (file:///Users/choongjaelee/.nvm/versions/node/v22.15.0/lib/node_modules/@anthropic-ai/claude-code/cli.js:1358:20090)
