REST API - Change Project Lead

Matt Benett

I am trying to change Project Lead by API, but I am getting the error:

{ "errorMessages": [ "Can not deserialize instance of java.lang.String out of START_OBJECT token\n at [Source: org.apache.catalina.connector.CoyoteInputStream@3e2799bc; line: 2, column: 5] (through reference chain: com.atlassian.jira.rest.v2.issue.project.ProjectInputBean[\"lead\"])" ]}

I am doing a PUT to here:

https://server/rest/api/latest/project/PROJKEY

Of this content:

{ "lead": { "key":"jsmith" } }

Any ideas please?

Hi,

Use the following payload instead:

{"lead":"username"}

Here is a working example using cURL:

curl -X PUT http://localhost:8080/rest/api/2/project/PROJECTKEY -d '{"lead":"username"}' -u "admin:secret" -H "Content-Type: application/json" -vvv

Kind Regards

Hello all.

The solution above doesn't work for me, at least using curl from Powershell. Doesn't matter what I do, I got an error (Unexpected character ('l' (code 108)):) this character is l of "lead". It means doesn't matter what I put after "-d", the first character, except the '{, will get this error.

Ok, let's go direct to the point. If you are stuck in PowerShell for this, follow what's worked for me (Powershell)

There is a Jira module for PowerShell, JiraPS, it has good commands to create issues, get information, and other functions you can check. But there are no commands for much other stuff. In this case, there is a special command, Invoke-JiraMethod. This basic process the rest API correctly in Powershell. To change the project lead, in my case is an offboarding scenario, so I want to deactivate the user, but we can't deactive a user that is a leader of a project. Using the same module, JiraPS:

Find projects that the user is leading:

$project_lead = Get-JiraProject | Where-Object {$_.LEAD -match "$user" }
$project_key = $project_lead.key

Then I use foreach to loop into the result to change the lead of all projects this user is leading.

basic the command is

$body = '{"lead": "$newlead_username"}'
$parameter = @{
Uri = "$(Get-JiraConfigServer)/rest/api/latest/project/$project_key" #$project_key is the project achronismus
Method = "PUT"
Body = $body
}
Invoke-JiraMethod @params

Finally, deactivate the user

Set-JiraUser -User $user -Active $False

Using the REST API, I cloned a project, and the suggested answer with the payload {"lead", "username"} comes back with a success status of 200, but the UI does not show an update. So, I did a fetch after the update and observed the update took place as expected. Why UI does not show it remains a mystery until someone comes up with more details.
