FATAL ERROR: Ineffective mark-compacts near heap limit Allocation failed - JavaScript heap out of memory

[alanwilter]

A month ago I was able to deploy it without any issues.

Using:

{
  "devDependencies": {
    "serverless": "^3.27.0",
    "serverless-plugin-warmup": "^8.2.1",
    "serverless-prune-plugin": "^2.0.2"
  }
}

sls deploy -s dev-live --verbose
...
Excluding development dependencies for function "warmUpPluginDefault"

If I comment out lines:

    warmup:
      default:
        enabled:
        #  - dev-live
        #  - prod-live

Deployments go without a hitch.

I've checked out the repo in a new folder and all seem to have worked. Trying to find out what's wrong with my original working folder.

Hmmm strange...

I can't think of any reason for a serverless deployment to exhaust Node's memory.

I'll close this since it seems resolved now.
