Failed deploy: SyntaxError: Unexpected token '?='

I have a failed deploy. Any ideas how to fix it?
Thanks in advance :slight_smile:

Render includes Node.js with a default version of 14.17.0. If you need to use a different Node.js version for your application, you can easily make this adjustment within the platform. To do so, navigate to your application’s environment settings on Render, and create an environment variable called NODE_VERSION. Set the value of NODE_VERSION to match the specific Node.js version that you have thoroughly tested with your application.
