No ACTIVATION_KEY or LICENSE_KEY Set

If you see the following error message in Document Engine container logs, you’ll need to set a valid ACTIVATION_KEY:

No `ACTIVATION_KEY` or `LICENSE_KEY` set. You need to set one of them in your `docker-compose.yml`. https://pspdfkit.com/guides/document-engine/deployment/product-activation

See our product activation guide for more information on how to do this.
