Azure app services failed to run deployment command

Question

In the past I'm able to deploy my NodeJS web app on deployment slots for my app service. The deployment was done in the Deployment options blade in portal.azure.com, by configuring the git repository and branch, etc.

Recently (last few days since last week 1-15-2018), all deployments failed, including those branches that have the latest production. The failure seems to be due to Azure running npm install based on what's in the package.json file.

In Kudu portal, it's confirmed that deployment ended with errors since the node_modules folder contains 0 items.

As I mentioned, I even created a temporary deployment slot, configure its deployment options by pointing to a git branch that represents current production, so there's no new code, no new packages, no new anything. It's exactly as production that is currently running.

It appears something related to Azure. Has anyone experienced something similar or know a solution? Has something in Azure changed recently?

Here's the activity log that's captured:

npm ERR! 404 Not Found: ansi-styles@https://registry.npmjs.org/ansi-styles/-/ansi-styles-2.2.0.tgz

The error you got means one of your dependencies was trying to fetch unavailable version of ansi-styles 2.2.0. In this case, you'll need to find out this dependency and update it to fix this issue.

For reference: NPM throwing 404 error for ansi-styles package.
