Azure Video Indexer - Cannot get the insights widget to work

Question

I'm new to using Azure Video Indexer and have been playing around with the code samples to try out the service. So far, everything works great except for one thing - no matter what I do, I am unable to get the video insights widget to load correctly as an embed.

The issue does not occur with the sample videos, it only occurs with videos that I've uploaded to my account. My account is not a trial account, I've upgraded to the 'unlimited' option. I've tried setting the videos to both 'private' and 'public' to eliminate the possibility of a permissions issue.

Here's my code for reference:

<iframe width="580" height="780" src="https://www.videoindexer.ai/embed/insights/8e5948a6-5941-4ae7-9354-361ad8f3a013/9wf72lt1od/?&locale=en&location=eastus2" frameborder="0" allowfullscreen></iframe>
    <!-- Add the VI mediator to communicate between both widgets -->
    <script src="https://breakdown.blob.core.windows.net/public/vb.widgets.mediator.js"></script>

And this is what I get:

What am I doing wrong? Or is there something wrong with the platform?
