AkousaERR_ASYNC_CALLBACKA non-function value was passed where an async callback was expected.
A Node.js API that expects a callback function received a non-function value (undefined, null, number, etc.). This usually means the callback argument was omitted or the arguments are in the wrong order.
Pass a valid callback function. Check the argument order matches the API documentation. Ensure the callback variable is defined. Use the promisified version (util.promisify or fs.promises) if you prefer async/await.
