fs Error: EISDIR: illegal operation on a directory, read

I'm getting "Error: EISDIR: illegal operation on a directory, read" after trying to read the content of a .json. This is how I'm trying to access the file. I'm using the FileSystem of node js.

fs.readFile( path, ( err, fileData) => {

                if (err) {

                    throw err;
                }
                else {

                    return fileData;
                }
            });

While debugging I can see that the error is thrown before the if statement.

Any idea?

I get the same error, after debugging a lot I finally figured out my path is not generated correctly, generating the path properly worked for me!

I recommend to generate file path before in separate variable using path package to get actual path, console.log your variable to see what actually path is:

import path from "path";

const { fileName } = req.query;
const filePath = path.resolve(__dirname, "../../../../your_folder");
console.log('filePath: ', filePath);

fs.readFile(`${filePath}\\${fileName}`, (err, fileData) => {
   if (err) {
     throw err;
   }
   else {
     console.log('fileData: ', JSON.parse(fileData));
     return fileData;
   }
 });

Note: I used double back slashes (because of string literal) to get one back slash '\' not forward slash '/'

Hope it helps!

Maybe the path to the file is not the right one, make sure the path of your file looks like the one that appears in the following code:

const fs = require('fs');

fs.readFile('PATH_TO_YOUR_FILE/File_Name.json', (err, fileData) => {
    if (err) {
        throw err;
    } else {
        console.log(JSON.parse(fileData));
    }
});
