I just updated from Drupal 8.9.16 to Drupal 9.2.0. It worked fine in my test environment, but when I try on the production environment, I get the following error.
requires the 'core' key not be set in core/profiles/testing_install_profile_dependencies_bc/testing_install_profile_dependencies_bc.info.yml
I have looked in the core directory and do not have this path, so I am not sure why it is complaining about it. Googling, I saw this was part of Drupal 8.8.
Is the content of YAML files stored in the database somewhere?
I am stuck with a site that displays a WSOD. I am hoping someone else has come across this issue and can help me fix it.
These are the first lines of the stack trace.
