**PDF.js Express Version**

**Detailed description of issue**  
I am having issues with a error that keeps up recurring on my production environment. I have followed step three from this documentation [[[Open a document, add annotations, download | Documentation](https://pdfjs.express/documentation/use-case/upload-download)]]. I know that i would probably have to add in my License key, Client Key and Server Key to remove all water marks. When i try and click on this external button it fails out on the merge giveening me the error message below. I have check my domain to make sure that I have set it correctly. Which it is. It seems to be working on the viewer it self just not on the external download.  
Thanks For you help  
**Expected behaviour**  
Right now i am getting this error in my console

**Does your issue happen with every document, or just one?**  
Every Document

**Link to document**  
{Provide a link to the document in question if possible}

**Code snippet**  
This is the code snippet that i use to download the PDF externally from the viewer.

```javascript
const pdfUtils = new ExpressUtils({
    serverKey: "Server_Key",
    clientKey: "Client_Key",
});

async function _DownloadContracts() {
        try {
            setVisibilityShowen(true);
            const xfdf = await instance?.annotManager.exportAnnotations({});
            const fileData = await instance?.docViewer.getDocument().getFileData({});

            if (xfdf && fileData) {
                const resp = await pdfUtils.setFile(fileData).setXFDF(xfdf).merge();
                resp.license = "License_Key";
           
                
                const mergedBlob = await resp.getBlob();
                FileSaver.saveAs(mergedBlob, selectedFile.name);
            }
        } catch (e) {
        } finally {
            setVisibilityShowen(false);
        }
    }

```

I have also hid the resp.license = “License\_Key”; line and still got the error above.

Hi,

Can you send me the domain from which you are sending requests from? You can send in a DM if you don’t want to share publically.

Thanks!
