>>> [!note] Migrated issue <!-- Drupal.org comment --> <!-- Migrated from issue #3573445. --> Reported by: [michaelb](https://www.drupal.org/user/2309046) >>> <p>Hello,</p> <p>I am trying to use an AI task within ECA using the ai_integration_eca module.<br> When triggering an "AI Chat" action that includes a value in the field "Specific configuration for the model", the execution fails with the following error:</p> <p><strong>Error invoking model response: Unknown parameter: 'system_name'</strong></p> <p>I followed the example provided in the field description and simply copied the configuration:</p> <p>system_name: system<br> system_prompt: you are a helpful assistant</p> <p>Without this specific configuration, the ECA task runs correctly. The error only appears as soon as this configuration is added.</p> <p>I am not sure whether this is a bug, or a misuse on my side, so I am opening this issue mainly for clarification.</p> <p>Steps to reproduce :</p> <p>1. Create or edit an ECA model.<br> 2. Add an action "AI Chat" (ai_integration_eca).<br> 3. Fill the field "Specific configuration for the model" with:</p> <p>system_name: system<br> system_prompt: you are a helpful assistant</p> <p>4. Trigger the ECA process.<br> 5. The execution throws the error:</p> <p>Error invoking model response: Unknown parameter: 'system_name'</p> <p><strong>Additional question</strong></p> <p>Are Drupal tokens supported inside:</p> <p>* the prompt field?<br> * the "Specific configuration for the model" field?</p> <p>Regards</p>
