Here's the scenario. I keep all our sites on our server updated via Composer. Standard procedure is to run
composer update drupal/* --with-dependenices
Then I run
drush updb
Next
composer update drupal/core webflo/drupal-core-require-dev --with-dependenices
and drush updb once more.
When doing this to move from Drupal 8.7.10 to 8.8.0, I first learned that I needed to update Pathauto module. Good. I do that. But when I go to admin/reports/updates; I get the message "The website has encountered an error. Please try again later."
Log messages showInvalidArgumentException: Host must be a string in GuzzleHttp\Psr7\Uri->filterHost() (line 611 of /home/jonestownag/vendor/guzzlehttp/psr7/src/Uri.php).
If I refresh the site several times I can get the page to load but no updates show.

Google has not been much help. And I really want my sites stable. What can I do?
