hello! has anyone encountered this error when migrating an existing stack from pulumi docker v3 (specifically 3.1.0) to 4.0.1?

Diagnostics:
  docker:index:Image (api-image):
    error: expected '::' in provider reference ''

building a stack from scratch seems to work well

Looks like a malformed id. You could export your stack and look at all the ids of your Image resources.

let me double check, but i’d expect new stacks would fail too, but those work well

I ran into this. My statefile never had a provider for the docker Image. Apparently this was valid for v3 but v4 requires it

thanks for the info mike! ok ill try out removing the images from the state for now. i can also create an issue for it in case it’s a simple fix, or at least have it documented on the version 4 release notes

That's be great if you could create the issue! Since you have the details more handy given that my state is long fixed 🙂

hi folks! yes, it appears that because the Image resource is newly schematized in the provider, there may in fact be a manual stack update needed. As far as I know, we don't have a less manual resolution available, as this is truly the first time we are doing this to one of our resources. Of course I will double check with the team. Thanks everyone for your patience. I updated the issue Brian filed [here](https://github.com/pulumi/pulumi-docker/issues/563#issuecomment-1485681867) and also added the steps to the migration guide for v4. 🙇‍♀️
