Unable to send email to external reviewer

[Perficient-DomKenney]

When creating the external review link, the share button correctly pulls up the email modal & I am able to populate this.

However, once I hit the send button it fails to ever send out.

This appears to be happening on multiple clients, and their configuration regarding AdvancedReviews is the same as the test provided in this repo (so far as I have been able to identify).

Hi, any callstack?

The only error I receive is the following output from Application Insights:

No breakpoints or logs are generated on any DXP environment, but debugging locally I can see this. This is the only fragment related to this behavior I have been able to identify.
