Automation with custom field (JSON), error: data was not an array

[Ольга Хомякова]

Hi everyone!

I'm trying to add all users from the role in the project to the custom user field. But it gives an error "data was not an array"

My JSON looks like this:

{
"fields": {
"customfield_10301": "ProjectRole_10505"
}
}

What am I doing wrong?

Thank you in advance guys!
Kind regards,
Olga

Hi,

Welcome to the community

You need to passe each user one by one like this:

    "fields": {
        "customfield_10301": { "name": "username" }
    }
}
