New data model form throws an error on submission

[mrjmd]

I just spun up my first Reservoir install! Lots of cool stuff in there to explore.

I did run into an issue trying to create a new data model / content type, got a hard "unexpected error" page when I submitted the form. The error message in the logs is below.

Drupal\Core\Field\FieldException: Attempt to create a field without a field_name. in Drupal\field\Entity\FieldConfig->__construct() (line 104 of /Users/matt/Sites/reservoir/docroot/core/modules/field/src/Entity/FieldConfig.php).

It's worth noting this was from the admin/models/add form, and the new content type was successfully created.

Wow, that's weird! We'll try to reproduce and fix this.

I'm 90% certain this is related to acquia/reservoir@a2c5831.

BTW, this belongs on https://github.com/acquia/reservoir, but … I don't think GitHub allows us to move this issue to another project?
