How set 'Request Participants' custom filed via PowerShell JiraPS?

IT Department

I was able to find that 'Request Participants' is field customfield_12703 but I don't know what kind of object should I pass to New-JiraIssue Fields parameter.

 

I've tried:

{

    customfield_12703 = '<userName>'

}

customfield_12703 = @(@{
    value = @{emailAddress='<userEmail>'}

})

etc

Command even ended successfully but the 'Request Participants' field isn't populated...

I was able to get the following to work using the acountId of the customer accounts for the Request Participants field. I tried using the emailAddress and the displayName but those did not work.

$Parameters = @{
    Project = "PROJECT_NAME"
    IssueType = "ISSUE_TYPE"
    Summary = "Test from JiraPS"
    Description = "This is another test from JiraPS module in PowerShell"
    Fields = @{
        customfield_12703 = @(
            @{ "accountId" = "qm:9c011c16-b415-11ec-b909-0242ac120002:93b32d64-a5c1-5829-77e5-0f98ec212451" }
            @{ "accountId" = "qm:9c011c16-b415-11ec-b909-0242ac120002:2b6af13f-67c9-fc38-0b17-cf341573e082" }
            @{ "accountId" = "qm:9c011c16-b415-11ec-b909-0242ac120002:4374ea62-350d-f265-1e6e-8e6b288d3fe3" }
        )
    }
}
