Apex Up - Error: Cannot find module 'debug' - node.js

Question

The error persists after I CLI enter up stack delete and also when I CLI enter up in an alternative directory that I know worked previously. Error also persists if I revert inconsequential changes to a prior working state.
Changing the name field in the up.json file results in a successful deploy in the alternate directory! But something about deploying with the same alternate name from my problem directory causes the issue again.
npm i -S debug does not help.
Has anyone else experienced and resolved this problem somehow?
UPDATE: Getting closer. By commenting things in and out I've got the error
"Error: Cannot find module './src/resolvers'"
From line:
var resolvers_1 = require("./src/resolvers");
Changing to:
var resolvers_1 = require("./resolvers");
fixes the single import issue, but not the remaining...
I'd move the index.js file to the src directory and keep a flat file structure... but I have complex reasons I can't do that.

Despite additional issues blocking me, this webpack configuration worked for me:
// webpack.config.js
module.exports = {
entry: "./src/index.ts",
module: {
rules: [
{
exclude: [/node_modules/],
test: /\.tsx?$/,
use: "ts-loader"
},
{
include: /node_modules/,
test: /\.mjs$/,
type: "javascript/auto"
}
]
},
node: false,
output: {
filename: "index.js",
path: path.join(__dirname, "dist")
},
resolve: {
extensions: [".tsx", ".ts", ".js", ".mjs"]
},
target: "node"
};
