Error: Cannot find module core-js/proposals/array-flat-and-flat-map

[mtmckenna]

Intended outcome:

Trying to install/run a serverless app using apollo-server-lambda.

Actual outcome:

When running apollo-server-lambda v2.3.3, I get an error when running the server in apollo-env. That error looks like this:

'Error: Cannot find module \'core-js/proposals/array-flat-and-flat-map\'',

I think the issue is that apollo-env pins the core-js dependency to ^3.0.0-beta.3, which currently resolves to 3.0.0-beta.12. From the looks of it, the issue is that, between beta.11 to beta.12, the array-flat-and-flat-map.js has moved?

How to reproduce the issue:

I think running any app with apollo-server-lambda v2.3.3 should do it.

Versions

apollo-env 0.3.0

Thanks for submitting this issue @mtmckenna, I was about to do the same.

We have an example of deploying apollo-server with ZEIT Now and the pinning issue caused our example – which also allows users to initialize projects from – to break and make our CI fail.

I highly suggest pinning a specific version (no ^) when using beta versions to avoid unnecessary breakage.

I had to install and pin a specific core-js version to fix this: https://github.com/zeit/now-examples/commit/2583cd773b6e6e04f827c1d899689ef913e237ad

Looks like a PR was submitted! #961

CI stopped working suddenly here with this error some time on Friday midday PST .. very serious!!! We are using apollo graphql which I guess depends on this, but I thought we had all our versions locked in package.json, need to understand better why we were impacted....

Thanks for jumping on this so quickly! We've pinned the core-js dep and rereleased. Fixes should be in apollo-env@0.3.1

I believe apollo server express (and likely other apollo-server-x) need to be updated as part of this fix - the dep chain looks like so and as such, I can't update to apollo-env@0.3.1

apollo-server-express@2.3.3
  └─┬ apollo-server-core@2.3.3
    └─┬ @apollographql/apollo-tools@0.3.0
      └── apollo-env@0.3.0

Can you rollback?
Can you test before publishing breaking changes?
