Problem/Motivation

Executing the action Form field: set as disabled (eca_form_field_disable) results in an Access denied error.

The log message:

Access denied to Form field: set as disabled (eca_form_field_disable) from ECA Test (test) for event Drupal\eca_form\Event\FormBuild:
- event (DTO)
- machine-name (string "eca.form.build")
- entity (Entity node/article//)
- node (Entity node/article//)
- user (Entity user/1/admin)
- form (DTO)
- id (string "node_article_form")
- base-id (string "node_form")
- operation (string "default")
- num-errors (integer "0")

Steps to reproduce

1. In a fresh Drupal 9.5 site, install and enable ECA and the ECA Form submodule.
2. Create a model that includes the Form field: set as disabled action.
3. Test the model by performing an action that triggers the event.

I tested this on a new Drupal install that I set up to learn about the ECA module and haven't been able to get the eca_form_field_disable action to run successfully.

I've tried a few different events (without conditions), like content_entity_prepareform and form_form_after_build, but haven't been able to get 'set as disabled' to execute. I've also tried this with 'Execute models with user' (with uid 1) and with the 'switch user' action.

I've also tried the same events with different actions, for example Form: set method (eca_form_set_method) has run successfully.
