How do I search using powershell on premise TFS ? #38

I am running TFS 2017 on prem update 2

$tfsUrl = 'https://tfs:444/tfs'
$projectId = 'd18ff858-xxxxxxxx'
$teamId = '9907188a-xxxxxxxx'
$tfsRepos = "$tfsUrl/Common/$projectId/_apis/search/codesearchresults?api-version=4.1-preview.1"
$secureCredential = Get-Credential
$allResults = (Invoke-RestMethod -Uri $tfsRepos -Method Post -Credential $secureCredential).value
$allResults= $allResults | Select -first 20

I am getting this error

Invoke-RestMethod :
Page not found. - Microsoft Team Foundation Server
