Access disk data

Hi everyone,

I’m just starting with Render.
I have a disk and i can upload a file on it. The file is also on a database.
However, i can’t get the files.

Here are the requests i use, to upload a file and to get a file.

Thanks for your help! :slight_smile:


const mountPath = '/var/data';
exports.upload = async (req, res) => {
  let id = Math.floor((1 + Math.random()) * 0x100000000000)
  if (!req.files || Object.keys(req.files).length === 0) {
    return res.status(400).send('No files were uploaded.');

  const sampleFile = req.files.file;  
  const destinationPath = path.join(mountPath,;, (err) => {
    if (err) {
      console.error('File upload error: ' + err);
      return res.status(500).send('File upload error: ' + err);

      `INSERT INTO files (id, user_id, name, type, size, content, uploaded_at) VALUES (?, ?, ?, ?, ?, ?, NOW())`,
      [id, req.userData.userId,, sampleFile.mimetype, sampleFile.size, sampleFile.content],
      (dbErr, result) => {
        if (dbErr) {
          console.error('Database insertion error: ' + dbErr);
          return res.status(500).send('Database insertion error: ' + dbErr);
        res.send('File uploaded and saved to the disk!');

//Get file

exports.getFile = (req, res, next) => {
  const graphId = req.params.graphId;
  const filePath = path.join('/var/data/', graphId) 
  if (fs.existsSync(filePath)) {   
    res.sendFile(filePath, (err) => {
      if (err) {
        return res.status(500).send('Error while sending the file');
  } else {   
    res.status(404).send('File not found');

Hi there,

What error do you see when trying to download the file? You can use the shell tab on our dashboard to inspect what files you have in /var/data. This will allow you to ensure you are passing the correct value for graphId, which would need to be the filename.

Hi Keith,

So you saved me…, thanks !
The problem was that i was trying to get the file with its id, and not by its name.

Thanks again!
