adobe blocked by CORS policy but URL is in allowed domain for API settings?

[Joseph24206727ky4h]

Im having some issues with the embed API. the PDF pops up and then instantly disappears when I check dev tools I see the below error.

Access to fetch at 'https://viewlicense.adobe.io/viewsdklicense/jwt' from origin 'https://download.militaryonesource.mil' has been blocked by CORS policy: No 'Access-Control-Allow-Origin'.

But I'm not sure why i am getting this error as the allowed domain is set to allow this URL  (download.militaryonesource.mil) in the API config.

<div id="adobe-dc-view" style="width: 800px;">

</div>

<script src="https://documentcloud.adobe.com/view-sdk/main.js"></script>

<script type="text/javascript">

const queryString = window.location.search;

const params = new URLSearchParams(document.location.search);

document.addEventListener("adobe_dc_view_sdk.ready", function() {

var adobeDCView = new AdobeDC.View({

clientId: "SOMECLIENTID",

divId: "adobe-dc-view"

});

adobeDCView.previewFile({

content: {

location: {

url: "https://download.militaryonesource.mil/12038/MOS/ResourceGuides/The_Days_Ahead_Spanish.pdf"

}

},

metaData: {

fileName: "SPA.pdf"

}

}, {

embedMode: "IN_LINE"

});

});

</script>

Is this online where I can take a look?

I am having this same issue, everything was working for a year+ and then stopped recently with this CORS error 

[Raymond Camden]

As I asked the other person, is this online where I can see?

Ray,

This turned out to be an issue on our end related to a Chrome extension. Sorry about that. 

[Raymond Camden]

No worries!

It's likely the same issue here. I created a new project with the same domain settings as a working project, but we often encounter the error "domain is not authorized," and sometimes we see a CORS error.

https://sanofi-campaign.wenk-media.com/Medical-News/mCRPC-01.

Testing your link, I get the error where the client id is not valid. So can you share a screenshot of your credentials from the dashboard, specifically the host name you specified? If you specified www.wenk-media.com, note that sanofi-campaign is a different subdomain and would not work. You would need to make a new client id and consider using just wenk-media.com.

[Twodot]

Please find attached a screenshot of the dashboard. The domain setting used is wenk-media.com. It seems that only the newly created project is not functioning properly, while the project created in July 2022 with the same domain setting is working fine.

[Raymond Camden]

Not quite sure what's happening here. It was a bit hard to get into your code as it's minified, but I see the right client id being used. If you were to make _another_ one and try again, do you get the same?

[Twodot]

Thanks for Ray's help.

I have identified the issue, the sdk script has been released with a new vesion.

previous script: https://documentcloud.adobe.com/view-sdk/main.js
lastest script: https://documentservices.adobe.com/view-sdk/viewer.js

The lastest sdk is compatible with older client id. However, if an older version of the sdk is used with a new client id, it will result in a domain setting error.

[Raymond Camden]

Ah, I didn't even think of checking for that - so it sounds like you are good if you just use the new version.
