Some customers are updating their Composer-managed sites to Drupal 8.8.x and are seeing this error:
CONFIGURATION SYNC DIRECTORY The directory sites/default/config does not exist.
If you are having this issue, you will need to change some configuration as documented here.
example-drops-8-composer (the starting template for all Composer-managed sites on Pantheon) includes this configuration in
settings.php . Any site built from this example (e.g. using either the No CI workflow or the Build Tools workflow) will need to be updated.
Happy to answer any questions! Happy Friday!
