react-starter | starter kit for building React | Frontend Framework library

I've run into a roadblock trying to get my web app to run on a Windows Azure App Service.

My app has a Node.js/Express back-end written in TypeScript (compiled with tsc, not Webpack) and uses Sequelize to connect to a SQLite 3 database, stored locally. The front-end is a React app built on Create React App.

The problem is that when sequelize tries to require sqlite3, a MODULE_NOT_FOUND error occurs, causing sequelize to throw a "Please install sqlite3 package manually". (See full stack trace below.)

The sqlite3 folder with the expected files is clearly present in the node_modules folder in the Azure file system, so I really don't get how require("sqlite3") could be failing.

Here's what I've tried so far:

1. I tried pretty much every suggestion in this sequelize issue.
2. I searched StackOverflow, but most of the questions relate to Electron, which I'm not using. Nonetheless, I read most of them, and tried any of the suggestions that seemed relevant.
3. I made sure the version of node on my development machine is the same as on my Azure Window App Service (14.16.0).
4. I tried deleting the node_modules folder and running npm install --production using the Azure console.
5. I tried running npm rebuild from the Azure console.
6. I tried running npm cache verify from the Azure console.
7. I tried globally installing sqlite3 using npm install -g sqlite3 from the Azure console, but that action was forbidden by Azure.
8. I tried installing sqlite3 from the source using npm install sqlite3 --build-from-source.
9. I added console log statements to node_modules/sequelize/lib/dialects/abstract/connection-manager.js to verify that the module name passed to the require statement was "sqlite3", and it was.
10. I tried replacing moduleName with the actual string, "sqlite3".
11. I checked to make sure all the sqlite3 files in my App Service file listing matched the ones installed on my development machine.
12. I probably tried a lot of other things I'm not remembering right now!

Needless to say, none of these things made any difference. Every time I checked the logs, the error was the same (and I checked the timestamps to make sure the logging system was actually working.)

Here is the full stack trace:
