Hi there,

Are you able to point me to the URL where you are seeing this issue? The only place we have an error message like that is in our rest API utilities - so I do not believe this is coming from Express itself.

Do you have some code like this somewhere?

import Utils from '@pdftron/pdfjs-express-utils'

const util = new Utils({})

Not providing license keys to this constructor will show that warning.

Thanks!
Logan

Yes, we have this

     import ExpressUtils from '@pdftron/pdfjs-express-utils'


            let element = document.getElementById('viewer');

            WebViewer({
                licenseKey: 'my_licensekey',
                path: '/pdfjs-express',
                initialDoc: pdf_url,
                ui: 'legacy'
            }, element).then((instance) => {
                const { docViewer, annotManager } = instance;
                this.webviewer_instance = instance;
                this.webviewer_instance.utils = new ExpressUtils()
                
            });

Where should we define again the license key?

Hi there,

Thanks for the code and the link. I do not see a watermark on your viewing, which means your express key is working as expected.

The log you are seeing is coming from this line: this.webviewer_instance.utils = new ExpressUtils()

You are instantiating the library without an API key (which is OK - the log is just letting you know). Here are the docs for the library.

Thanks!
Logan

But all files are being received with the watermark text: “PDF.js Express Dev mode” in red color

Is it because no API key is provided?

Hi there,

Yes, the REST API needs a separate license key which you can get from PDF.js Express.

See this page for more info.

Thanks,
