serverless: new `aws:accountId`, `aws:region` variables cannot be referenced/are failing to resolve

The documentation describes use of the aws:accountId and aws:region variables here. These were introduced in version 2.50.0. In version 2.54.0, these are failing to resolve with the following error message:

Invalid variable reference syntax for variable aws:accountId. You can only reference env vars, options, & files. You can check our docs for more info.

We need to be able to have the serverless version managed by package.json as we have many serverless projects and cannot maintain them all in lockstep on the exact same serverless version. Any ideas?

IIRC yarn is interfering with Node.js internals that are responsible for modules resolution, and that most likely causes that.

I would strongly suggest to rely on package manager that does not do that, e.g. you won’t have such issues when running serverless via npx that’s installed with npm (npx will also run project local version for you)

@lwoodson it looks that for some reason new variable resolver doesn’t pick up. It’s possible if there are issues with some vars resolution, still you should be also notified of that, and I can’t see any remark of that in your logs, and that’s puzzling

Let me try to reproduce it locally
