html - How to resolve the error that appears when previewing Office files?

Question

I'm trying to view Word, Excel, or PowerPoint using Office Web Viewer.
I'm trying to display it using the code below.
The data to be displayed is placed in Blob.

code:

<iframe src = "https://view.officeapps.live.com/op/embed.aspx?src=(encoded URL)"> </ iframe>

However, when I check the console on Chrome, I get the following error.

DevTools failed to load SourceMap: Could not load content for https://c1-powerpoint-15.cdn.office.net/p/s/*********_PptScripts/otelFull.min.js.map: HTTP error: status code 404, net :: ERR_HTTP_RESPONSE_CODE_FAILURE

I don't understand why such an error is occurring.
Even if I click the URL described in the error, "There is no page" is displayed.
Is this a code issue?
I don't know the cause, and I don't know what to do.
Please tell me what I should do to eliminate this error.
If there is an official page that can be used as a reference, please let us know.
