API: Trying to set name of an appveyor project - api

Question

I am trying to create an appveyor project using powershell and set my own name.
function Invoke-AppveyorCreateProject {
param (
[System.String] $appveyorProjectName,
[System.String] $repositoryName
)
# step 1, create project
$project = #{
repositoryProvider="gitHub"
repositoryName="esskar/$repositoryName"
isPrivate=$true
}
$json = $project | ConvertTo-Json
$project = Invoke-RestMethod -Method Post -Uri "$AppveyorApiUrl/projects" -Headers $AppveyorRestHeaders -Body $json -ContentType "application/json"
# step 2, update project
$project.name = $appveyorProjectName
$json = $project | ConvertTo-Json
$project = Invoke-RestMethod -Method Put -Uri "$AppveyorApiUrl/projects" -Headers $AppveyorRestHeaders -Body $json -ContentType "application/json"
}
# Globals
$AppveyorApiUrl = 'https://ci.appveyor.com/api'
$AppveyorApiToken = $env:AppveyorApiToken
$AppveyorRestHeaders = #{
"Authorization" = "Bearer $AppveyorApiToken"
"Content-type" = "application/json"
}
$AppveyorAccountName = $env:AppveyorAccountName
Invoke-AppveyorCreateProject "foo.bar" "repo1"
Step 1 works, the project is created, but when I try to change the name, i get an exception
Invoke-RestMethod : {"message":"Object reference not set to an instance of an object."}

when i try to set the name during creation in step 1, then name is not used, and project has the same name as without setting the name.

Answer 1

Use the following code for the Step 2:
$settings = Invoke-RestMethod -Uri "$AppveyorApiUrl/projects/$($project.accountName)/$($project.slug)/settings" -Headers $AppveyorRestHeaders -Method Get
$settings.settings.name = $appveyorProjectName
Invoke-RestMethod -Uri "$AppveyorApiUrl/projects" -Headers $AppveyorRestHeaders -Body ($settings.settings | ConvertTo-Json -Depth 10) -Method Put
