How to create testrun attachment in azure devops using rest api via powershell

Question

I am trying to attach a html file to a test run via rest api using powershell task in my yaml. following is the task that I have used.

- task: PowerShell@2

          inputs:
            targetType: 'inline'
            script: |
              $username = "" 
              $token = "" 
              $instance = "" 
              $teamProjectName = ""

              #create auth header to use for REST calls 
              $accessToken = ("{0}:{1}" -f $username,$token) 
              $accessToken = [System.Text.Encoding]::UTF8.GetBytes($accessToken) 
              $accessToken = [System.Convert]::ToBase64String($accessToken) 
              $headers = @{Authorization=("Basic {0}" -f $accessToken)} 
              $runId = "12345"
              Write-Host $runId
              $filePath = "d:\a\1\UIAutomation\report123.html"
              $Stream = "iVBORw0KGgoAAAANSUhEUgAAABgAAAAYCAIAAABvFaqvAAAAAXNSR0IArs4c6QAAAARnQU1BAACxjwv8YQUAAAAJcEhZcwAADsMAAA7DAcdvqGQAAABlSURBVDhP7cxBCsAgDERR739pG/CnGJI0FopQ8O2cjNP6R85QbeNQU7wT1dkijaQ3vkZoWElaoTeJojW01cYh0jwfgiFBV/lEjOZtacijN/nLkOBHhIaVDgn+Wdycp6FXzlCl9wt0Y0cAzHo/zgAAAABJRU5ErkJggg=="
              $uri = "https://$instance/$teamProjectName/_apis/test/Runs/$runId/attachments?api-version=5.1-preview.1"
              $body = @{
                        'stream' = $Stream
                        'fileName' = $filePath
                        'comment' = 'Test attachment upload'
                        'attachmentType' = 'GeneralAttachment'
                        }
              $testResult = Invoke-RestMethod -Method Post -ContentType 'application/json' -Headers $headers -Uri $uri -Body (ConvertTo-Json $body -Depth 10)
              Write-Host $testResult

I am getting an error in the console stating..

Invoke-RestMethod : {"$id":"1","innerException":null,"message":"Invalid filename specified. Filename contains invalid

character ':'.\r\nParameter name: fileName","typeName":"Microsoft.VisualStudio.Services.Common.VssServiceException,

[error]PowerShell exited with code '1'.

Can someone help me with how to invoke the rest post method for attaching a file to a testrun?

According to the error, it indicate Invalid filename specified.

From the official tutorial: Attachments - Create Test Run Attachment

filename    string    Attachment filename

It's just the file name which should not include file path. Suggest you first run the Post API on same 3rd-party tool like postman, check if it works well with Azure DevOps and then move it to powershell script.

You could also take a look at this blog: Azure DevOps Rest API. 17. Add Bugs and Attachments to Test Results which use code to call same Rest API.
