error message when updating an organization

[Olivier Rocher]

Hello team,

I am trying to create a, automation to set the "organizations" field when not set.

When ticket is resolved, if orgnization is empty a, I want to get the first orgnaisation the submitter belongs to, and set the organization accordingly.

Here is the rule 

{
"fields": {
"customfield_10002": [
{
"id": "{{issue.reporter.organizations.first.id}}"
}
]
}
}

I am getting th following error message : 

Erreur lors de la modification de tickets

KPHD-12395 (Spécifiez la valeur de Organizations dans un tableau (customfield_10002))

Tickets modifiés

KPHD-12395

Any idea ?

Thank you

Olivier
