Hey there, thanks for getting in touch.

It seems you have an error in your code. The signature needs to be generated with the API Secret, rather than key. Could you please update your code to the following and let us know if you are then able to upload?

  generatePresignedUrl() {
    const { cloudName, apiKey, apiSecret } = this.configService.get('cloudinary');
    const timestamp = Math.round(new Date().getTime() / 1000);
    const signature = cloudinary.utils.api_sign_request({ timestamp }, apiSecret);
    return `https://api.cloudinary.com/v1_1/${cloudName}/image/upload?api_key=${apiKey}&signature=${signature}&timestamp=${timestamp}`;
  }
