P4 "Warning, empty changelog. Have you run checkout?"

I am experiencing an issue where a declarative pipeline is not triggering a stage that uses a when block on a changeset due to an empty changelog

Warning, empty changelog. Have you run checkout?

The pipeline is a multi-branch configuration that uses perforce and has “Auto cleanup and sync” as part of the populate options. It uses streams.

When performing a scan (manually or via pollSCM) on the multi-branch it identifies the latest changelist correctly and triggers a build. The stage does not execute though due to the changeset condition with the above warning.

The when block looks like this:

when {
      anyOf {
          triggeredBy 'UserIdCause'
          changeset "**/*.cpp"
          changeset "**/*.h"
          changeset "**/*.cs"
          changeset "**/*.uproject"
          changeset "**/*.uplugin"
          changeset "**/*.uasset"
          changeset "**/*.ini"
      }
  }

Does anyone have any idea what might be the cause or areas to explore to try and remedy?
