Google Docs Embedded document giving errors

Question

When loading an embedded google document on my site. I get the following error on my website:

Uncaught ReferenceError: DOCS_timing is not defined
    at pub?

Link has been generated on google docs at https://docs.google.com/ .

My link is in the following format: (with ... meaning a large amount of seemingly random characters)

"https://docs.google.com/document/d/ ... /export?format=pdf";

This is my iframe that I have been using and I would expect it to work. This in in JSX.

<iframe
        name={"Cv"}
        src={source}
        onLoad={loadingDone}
        style={styleiFrame}
        allow="picture-in-picture full">
</iframe>

Cv shows up nicely, but it gives those errors every now and then.
