Please help!

Hello, can you please tell us the output of
console.log(__dirName)
If you are running this without changing the directory this error will be expected because you cannot write to the file “/{id}.txt” which is one directory up from the default /app directory. Instead I would recommend you write to the current directory with a single dot or the .data directory.

I dont know what is that, can you help me by checking around my project ?
