ExternalError: TypeError: Load failed

What I’m trying to do:
My app has gotten a number of users and I am encountering a number of errors. I am working with Jay and Stu on them and sent an email to Anvil support, where Ryan asked me to post about them in the forums. We have checked each of these extensively and couldnt solve them, so would love support!

Here I have an interesting case where there is 0 info in the logs. My own error handler caught this though. The logs are placing this as coming from the US, where I am certain I dont have any users.

Error: ExternalError: TypeError: Load failed

I saved this stacktrace both times:
