No help needed. Posting this on the community site to help other Fly users who may run into the same issues.
Last time I deployed our Node app to Fly was a few months ago. Has been running fine.
Yesterday, I added 2 regions in US and that went well.
Then, I tried to deploy new version of our super simple Node app (works fine on local) with flyctl deploy and this failed:
Executing build process
npm WARN read-shrinkwrap This version of npm is compatible with lockfileVersion@1, but package-lock.json was generated for lockfileVersion@2. I'll try to do my best with it!
cdnplanet-nodes@0.0.1 /workspace
`-- UNMET DEPENDENCY follow-redirects@1.14.1
npm ERR! missing: follow-redirects@1.14.1, required by cdnplanet-nodes@0.0.1
vendored node_modules have unmet dependencies: npm list failed: exit status 1
Upgraded Node and npm on local machine, specified Node and npm versions in package.json so to ‘force’ the paketo buildpack to use those Node and npm versions.
This solved the issue.
But, deploys still fail.
Tried several times, snippet of last attempt’s output in terminal:
...

You can detach the terminal anytime without stopping the deployment

Troubleshooting guide at https://fly.io/docs/getting-started/troubleshooting/
Searched on Google and ended up here on SO: node.js - Error: Cannot find module '/workspace/server.js' - Stack Overflow
Added "start": "node app.js" to my scripts in package.json and this solved the issue.
