Create pipleine in Azure devops by rest API failed – Value cannot be null. Parameter name: repositoryName

I am tring to create Azure devops (tfs) Pipeline by rets API as described here: https://learn.microsoft.com/en-us/rest/api/azure/devops/pipelines/pipelines/create?view=azure-devops-rest-6.0

Request url: https://tfs.xxx/tfs/Projects/xxx/_apis/pipelines?api-version=6.0-preview
Request body:

{   
    "folder": null,   
    "name": "pipeline-made-by-api",   
    "configuration": {     
        "type": "yaml",     
        "path": "build.yaml",     
        "repository": {       
            "id": "xxx",       
            "name": "xxx-repo",       
            "type": "azureReposGit"     
        }   
    } 
}

I got error 400 with response:

{"$id":"1","innerException":null,"message":"Value cannot be null.rnParameter name: repositoryName","typeName":"System.ArgumentNullException, mscorlib","typeKey":"ArgumentNullException","errorCode":0,"eventId":0}

I don’t see any parameter called repositoryName in the documentation.

What am i missing?

Thanks!

    Pipeline yaml be located in specific repository, so you must provide the repository id. A simple way to get your repository id:

    azureDevopsRepositoryGet.ps1

    [CmdletBinding()]
param (
    [Parameter(Mandatory)]
    [string]$OrganizationName,
    [Parameter(Mandatory)]
    [string]$ProjectName,
    [Parameter(Mandatory)]
    [string]$RepositoryName,
    [Parameter(Mandatory)]
    [hashtable]$Headers
)

$uri = "https://dev.azure.com/{0}/{1}/_apis/git/repositories/{2}?api-version=7.0" -f $OrganizationName, $ProjectName, $RepositoryName

$response = Invoke-RestMethod -Uri $uri -Method 'Get' -Headers $headers

return $response

    Then you can pass the repository id into

    azureDevopsPipelineCreate.ps1

    [CmdletBinding()]
param (
    [Parameter(Mandatory)]
    [string]$OrganizationName,
    [Parameter(Mandatory)]
    [string]$ProjectName,
    [Parameter(Mandatory)]
    [string]$PipelineName,
    [Parameter(Mandatory)]
    [string]$PipelineYamlFile,
    [Parameter(Mandatory)]
    [string]$RepositoryId,
    [Parameter(Mandatory)]
    [string]$RepositoryName,
    [Parameter(Mandatory)]
    [string]$BranchName,
    [Parameter(Mandatory)]
    [hashtable]$Headers
)

$uri = "https://dev.azure.com/{0}/{1}/_apis/pipelines?api-version=7.0" -f $OrganizationName, $ProjectName

$body = @{
    folder        = ""
    name          = $PipelineName
    configuration = @{
        type       = "yaml"
        path       = $PipelineYamlFile
        repository = @{
            id   = $RepositoryId
            name = $RepositoryName
            type = "azureReposGit"
        }
    }
}| ConvertTo-Json -Depth 5

$response = Invoke-RestMethod -Uri $uri -Method 'Post' -ContentType 'application/json' -Headers $headers -Body $body

return $response

    How to get header

    azureDevopsHearderGet.ps1

    [CmdletBinding()]
param (
    [Parameter()]
    [string]$UserName,
    [string]$PersonalAccessToken
)

$basicAuth = ("{0}:{1}" -f $UserName, $PersonalAccessToken)
$basicAuth = [System.Text.Encoding]::UTF8.GetBytes($basicAuth)
$basicAuth = [System.Convert]::ToBase64String($basicAuth)
$headers = @{Authorization = ("Basic {0}" -f $basicAuth) }
return $headers

    It appears the url https://tfs.xxx/tfs/Projects/xxx/_apis/pipelines?api-version=6.0-preview is not correct, at least there’s extra Projects.

    For On-Prem ADO server(tfs), please fix the url with below format:

    https://{instance}/{collection}/{project}/_apis/pipelines?api-version=7.0

    The api-version could be different based on different tfs version.

    On my ADO server 2022, below powershell script works. Please replace url and parameters, and try on your side.

    # Define your parameters
$token = "PAT"
$repositoryId = "repoid"
$repositoryName = "reponame"

# Convert PAT token to Base64
$base64AuthInfo = [Convert]::ToBase64String([Text.Encoding]::ASCII.GetBytes(":$($token)"))

# Define the API URL
$url = "https://{instance}/{collection}/{project}/_apis/pipelines?api-version=6.0-preview"

# Define the request body
$body = @{
    "folder" = "null"
    "name" = "test"
    "configuration" = @{
        "type" = "yaml"
        "path" = "build.yml"
        "repository" = @{
            "id" = $repositoryId
            "name" = $repositoryName
            "type" = "azureReposGit"
        }
    }
} | ConvertTo-Json

# Send the POST request
$response = Invoke-RestMethod -Uri $url -Method Post -Body $body -ContentType "application/json" -Headers @{Authorization=("Basic {0}" -f $base64AuthInfo)}

# Output the response
$response
