Acquia Insight incorrectly showing issues for modules

Issue

Acquia Insight is showing issues that module/s are disabled despite these being enabled on the site.

Example

  Core                          Internal Dynamic Page Cache (dynamic_page_cache)            Enabled    9.0.7
  Core                          Internal Page Cache (page_cache)                            Enabled    9.0.7

Cause

The module/s are missing a core property in their info.yml files. This appears to be a change introduced for core modules in preparation for Drupal 9.

The Acquia service (NSPI) which produces the Insight report, doesn't know what to do with modules that don't have the core property, so it ignores them. This will affect any module that adopts the new core_version_requirement property and does not also declare core.

Resolution

Acquia recommends ignoring the Insight reporting of these module/s and when addressed, a release note will be provided.
