Error parsing triggers: Cannot find module './db.json'

I’m trying to add image-sharp so i can automatically generate thumbnails. I’ve ran npm install at the functions level and added the following modules:

const functions = require("firebase-functions");
const gcs = require("@google-cloud/storage")();
const path = require("path");
const sharp = require("sharp");
const _ = require("lodash");
const os = require("os");

When I run firebase deploy I get this message at functions: preparing functions directory for uploading...

Error: Error parsing triggers: Cannot find module './db.json'
Try running "npm install" in your functions directory before deploying.

If i remove those new module dependencies from my index.js i don’t get the error.

@inlined - I think you’re code and dependencies are fine, it was dependency on my end (sharp@0.17.1) that wouldn’t install on GCF, once I upped my version of Sharp all was well.

Glad to hear you’re sorted out. We’ll look at updating the dependencies in the sample.
