Fill custom field with asset, in a team-managed project

Question

Dear all,

I am facing a strange issue with automation and custom fields.

Context:

I am under a team-managed project, hence there is no "screen" to add my custom field to. I added it directly from Project Settings, on my issue type IT.

The custom field is configured to be filled with an object from the assets defined in Jira Service Management.

Issue:

In my automation, I want to edit my issue and filled the custom field with a lookup objects. Unfortunatly, I get this error message:

---EDIT ISSUEAn error occurred while requesting remote informationBad RequestNo fields or field values to edit for issues (could be due to some field values not existing in a given project):KEY-205---The field is available in my project, as I can manually fill it on the issue KEY-205.Any idea? Thanks!Edit: adding automation screenshots:
