.get() attempting to grab from home dir (Linux) about express HOT 2 CLOSED

__dirname does not have trailing slash, so your problem is the string concatenation.

You can use path.join, which will build a path from segments by inserting platform-specific directory separator between the segments.

// const path = require("node:path");
app.get("/robots.txt", function (req, res) {
    res.sendFile(path.join(__dirname, "robots.txt"));
});

Yep, its a path construction issue.
