Error when trying to trigger AI Automator

Created on 3 September 2025, 13 days ago

Problem/Motivation

I tried creating an ECA model that automatically fills in a textarea field on a page node (field_seo_description).
It is supposed to take the whole node contents (full view mode), and use AI to create a summary out of that, and fill it in the aforementioned field.

However, when trying to use the "AI automator" action trigger, I'm getting the following error:
action "AI Automator Trigger" (eca_ai_automator_1fcddok): The submitted value in the Automator element is not allowed.

Steps to reproduce

Used module versions:

"drupal/ai": 1.2.0-alpha2
"drupal/ai_integration_eca": 1.0.0-rc2
"drupal/bpmn_io": 3.0.0
"drupal/eca": 3.0.2
"drupal/modeler_api": 1.0.x-dev
"drupal/token_entity_render": 2.0.0
"drupal/schemata": 1.0.0

Configuration for my field_seo_description field:

“Enable AI Automator”: checked
Automator type: LLM Text
Input mode: Advanced

Prompt:

Create an SEO-friendly summary of the page content, as provided within the context below.
The description should be in the same language as the provided body text.
If the context is not sufficient or empty, please just return an empty string.

Context:
Title: [node:title]
Body: [node:render:full]

Body token is provided by the token_entity_render module. It provides HTML output of the whole page. Not sure if this is the best approach, since I'd want only the text, not the HTML, but it's a start...

"Edit when changed": checked
“Automator worker”: ECA
"AI Provider": LLM Proxy (using lite_llm)
“Joiner”: Space

I created an ECA model, and dragged a start event on it - selecting "Update content entity" (bundle: node page)
The action is of type "AI Automator Trigger".

OK, this was caused by an issue in the configuration form where the default value was an empty string and the drop down looked like the first item was selected. I've fixed that by adding an empty option to the drop down and force the user to select an item explicitly.

Please test this in the latest dev release.
