RouteNotFoundException: Route "entity.commerce_license.add_page" does not exist.

Yup, I realized after I made the release I should have taken those out too!

Don't suppose you could post a patch of them commented out?

Thanks!

Removing the entire commerce_license.links.action.yml Cause getting

Do you maybe have a nonstandard setup? Because I did 'drush cr' with the latest release and it all worked fine.

I just did a drush cr on a site that's running the latest dev, and the licenses page loads fine for me.

Here is my stack using drupalvm:

Also using php7.0 with relocated doc root on pantheon it's breaking. Is there any particular reason we should keep a file which is not used at all?

We (Acquia) have just seen a customer hit the same problem with 8.x-2.0-alpha10 - corrected by the patch in #6.

Acquia Cloud uses the PECL YAML extension. We have a snippet for locating potential sources of the yaml_parse() exceptions on the following article, which helped us locate this issue: https://docs.acquia.com/article/yaml-pecl-serialization-errors

Some background on why this might affect some and not others is here: #1920902: Add a Drupal Yaml wrapper so we can default to PECL Yaml component if it is available

Let put this back in needs review...

Thanks @chriso for the explanation and @nikathone for the patch!
