AttributeError: 'NoneType' object has no attribute 'data_cached' with 10.1.1

[Andre601]

I'm not making an issue for this as I cannot be bothered to go through the steps of making a reproduction for this, and I also can't tell what the exact cause is to properly report.

In short does building a site fail with 10.1.1 being used alongside the Blog Plugin.

From what I can understand and gather does this relate to the plugin and possibly the date and time infrastructure changes made?
Could it possibly be the plugin not handling posts with already defined date front matter?

I consider this a critical issue to be fixed as this blocks any proper page building.

This is a bug and I have already fixed it. An update will be released tonight.

There are two temporary workarounds:

• Roll back to the previous version
• Configure the document-dates plugin in properdocs.yml, like this:

plugins:
  - document-dates:
      exclude: ['index.md', '*/index.md', 'blog/*']
