Service Binding: local dev method

Hi, I'm developing 2 workers for the same project/account, in a Service Binding fashion. When deployed, the workers A is successfully able to call B. But locally, the Service Binding is actually undefined. Anyone can help? I have no idea why it can't see each other when running locally.

This is my env during dev, for Workers A (caller):
[env.dev]
vars = { ENVIRONMENT = "dev", ENV = "dev" }
services = [
  { binding = "SERVICES", service = "workers-services", environment = "dev" }
]

And this is for Workers B (being called):
[env.dev]
name = "workers-services"
vars = { ENVIRONMENT = "dev", ENV = "dev" }

When I run with --remote (using Wrangler v3.0.0), I get this error: text: 'workers.api.error.service_binding_env_error: could not resolve binding "SERVICES":
environment "dev" not found for service "workers-services" [code: 10144]'

These are however separate project, one is Bundled (A) and one is Unbound (B). One is nodejs compat (B), one is not (A).

So, to summarize:
  • when running with --remote, it spits out the error message just a short time after starting
  • when running locally (which is the default since wrangler v3.0.0 I assume), the env.SERVICE is undefined
  • running live (after deploy), no problem.
