Download a single file from bit bucket repository using Powershell

[Chandramouli Puvvadi]

I want to download a specific file ("Web/Externals/Settings.txt") in a folder(which is not having git) from my bit bucket repository "TestRepository" with branch name "TestBranch".

Please suggest

Note: I need the file as it is.

function CheckOutDevFile($userName, $password, $CheckOutFilePath, $RepoUrl){
 $userNamePaswords = "$($userName):$($password)"
 $encodedCredentials = [System.Convert]::ToBase64String([System.Text.Encoding]::ASCII.GetBytes($userNamePaswords))
 $authorization = "Basic $encodedCredentials"
 $Headers = @{ Authorization = $authorization }

 Invoke-RestMethod -Headers $Headers $RepoUrl -OutFile $CheckOutFilePath
}


$userName = 'Your User name'
$password = 'Your password'
$CheckOutFilePath = 'Your out put location with file name'
$RepoUrl = 'https://{CompanyRepoUrl}/projects/{PojectName}/repos/{RepoName}/raw/{SpecificFilePath}?at=refs/heads/{BranchName}'

CheckOutDevFile $userName $password $CheckOutFilePath $RepoUrl

I have tried that and I get the following error:
