App Bundles feature: cannot unmarshal !!map into []config.AppBundle

[Nibroc00]

What happened?

Just upgraded to goreleaser v2.6.1-pro and wanted to use the new app_bundles feature but got an error saying

nibroc@julius:~/PROJECT$ goreleaser check
  • by using this software you agree with its EULA, available at https://goreleaser.com/eula
  • running goreleaser v2.6.1-pro
  ⨯ command failed                                  
    error=
    │ failed to load configuration: yaml: unmarshal errors:
    │   line 160: cannot unmarshal !!map into []config.AppBundle

I'll drop my attempt at using app_bundles but I have tried removing more and more fields and templates from app_bundles to see if I could pinpoint the issue but to no avail. Having any of the subfields of app_bundle filled will cause this error. I also tried looking at the schema-pro.json to see if I could find my issue as well, which also lead to nothing.

app_bundles:
    id: PROJECT-app-bundles
    name: '{{ .ProjectName }}'
    # name: '{{ .ProjectName }}-{{ .Arch }}'
    ids:
      - PROJECT-archives
    if: '{{ eq .Os "darwin" }}'

    # Must be a `icns` file.
    icon: '{{ .Var.IconsetPath }}'
    bundle: com.PROJECT
    mod_timestamp: '{{ .CommitTimestamp }}'

    # Templates: allowed.
    extra_files:
      - src: '{{ .Var.IconsetPath }}'
        dst: Contents/Resources/iconfile.icns

    # Since: v2.6-unreleased.
    # Templates: allowed.
    # Extra template fields: `AppName`, `BinaryName`, and `Bundle`.
    templated_extra_files:
      - src: '{{ .Var.PlistPath }}'
        dst: Contents/Info.plist

Closest thing I could find in the issues was here

How can we reproduce this?

1. Have a goreleaser file with a build and archive step
2. Add app_bundles: field with any of the sub fields filled in
3. Run goreleaser release or goreleaser check

Additional context

Apologies for checking "goreleaser check shows no errors" because that's a lie, but nothing I could do would remove the error.

Hey!

app_bundles is a list, so you need to do something like this instead:

app_bundles:
  - # <----- make it a list
    id: PROJECT-app-bundles
    # etc ...

Holy I knew I was missing something dumb! Apologies for wasting your time I should have caught that. You can delete this issue since it's not a bug.
