Clone of request object fails in v 4.11

[antonandreyev]

If you use clone method on request object in HTTP triggered function with POST method, an exception is thrown.

Happens in version 4.11.0, if you roll back to 4.10.0 the issue is gone.

Stack trace:

Result: Failure Type: Exception: Cannot clone object of unsupported type. Stack: DataCloneError: Cannot clone object of unsupported type. at new DOMException (node:internal/per_context/domexception:76:18) at structuredClone (node:internal/worker/js_transferable:126:26) at HttpRequest.clone (/home/site/wwwroot/node_modules/@azure/functions/dist/azure-functions.js:1878:25) at /home/site/wwwroot/dist/src/functions/HandleSlackAchievementCommand.js:26:82 at Generator.next (<anonymous>) at /home/site/wwwroot/dist/src/functions/HandleSlackAchievementCommand.js:8:71 at new Promise (<anonymous>) at __awaiter (/home/site/wwwroot/dist/src/functions/HandleSlackAchievementCommand.js:4:12) at handleSlackAchievementCommand (/home/site/wwwroot/dist/src/functions/HandleSlackAchievementCommand.js:24:12) at InvocationModel.<anonymous> (/home/site/wwwroot/node_modules/@azure/functions/dist/azure-functions.js:215:46)
