/files route bug

[Gabriel250903]

I've found a bug for the /files route to show all the files found in the directory and i encountered a bug, it throws this error whenever i try to go to "localhost:3200/files". I've actually managed to fix it and i can provide the working code as well.

Error:

TypeError [ERR_INVALID_ARG_TYPE]: The "path" argument must be of type string. Received undefined

}

Working code :

app.get("/files", async (req, res, next) => {
res.send(
await drive.list("/", {
skipFiles: false,
subFolders: false,
exclude: (a) => a.indexOf(".") === 0,
})
);
});
