Like Pipo mention, you need to add a version number after the carrot "^" to the repo reference in your composer require command: "'composer' 'require' 'pantheon-systems/drupal-integrations:^<add_version_here>' '--no-update'".

Here's the repor for themodule https://github.com/pantheon-systems/drupal-integrations where you can get the appropriate version (branch or tag).

Good luck.
