"Something went wrong." when test user in Microsoft 365 Developer sandbox attempts to add a custom Teams Bot

I have created a custom Teams chatbot (which references my own server), and I have it working with my admin account in my Microsoft 365 Developer sandbox.

However, when I log in as one of my test users and attempt to install the app, it gives an error, "Something went wrong." after this endpoint returns a 400:
https://teams.microsoft.com/api/mt/part/amer-03/beta/users/apps/entitlements

I have been down the path of trying to get my publisher domain verified, to try and eliminate that as a potential source of trouble, but it's been complicated by the fact that my main site is running webflow and so can't follow the verification steps. I'm trying to re-route it to a subdomain, but that similarly isn't being accepted.

Is there some other basic setting I'm missing that is preventing my test user from installing the app?
