# Fix the 'Upload preset not found' error in Cloudinary

> Fix the Cloudinary Upload preset not found error, a 400 Bad Request, by creating an upload preset in the dashboard and passing its name as upload_preset.

I was doing a test project that used Cloudinary as the image storage.

I ran into this issue when I tried uploading the image. I received a 400 Bad Request with this [JSON](https://flaviocopes.com/json/) message:

```
{"error":{"message":"Upload preset not found"}}
```

Turned out I didn't set up an **Upload Preset**.

You need to go in the Settings in your Cloudinary Dashboard, in the Upload tab you click "Add upload preset", and you add one. 

Then you use that preset name in your Cloudinary upload code.

For example I had a `canvas` object from an HTML canvas I wrote to, and this was the code to upload it to Cloudinary as an image:

```js
const base64Image = canvas.toDataURL()
const formData = new FormData()
formData.append('file', base64Image)
formData.append('upload_preset', '***THE_PRESET_NAME***')

fetch(`https://api.cloudinary.com/v1_1/***YOUR_CLOUD_NAME***/image/upload`, {
  method: 'POST',
  body: formData,
})
```

Tip: while testing you might choose to add an unsigned upload preset, as it simplifies the code.
