Unable to upload to Raw Repo using Powershell

Hi there.

I’ve got a Powershell script to upload a specified file to a raw repo in Nexus OSS 3.28.0 but it’s not working.

Not sure why I’m getting the following error…I suspect it’s my “BodyLines” composition but I’m struggling to fix it.

Invoke-WebRequest : [ { “id” : “*”, “message” : “No assets found in upload” }, { “id” : “directory”, “message” : “Missing required component field ‘Directory’” } ]

Powershell is below:

# Check on https://bgstack15.wordpress.com/2020/06/22/nexuslib-ps1-powershell-library-for-uploading-files-to-nexus-raw-repository/ for an example

    [Parameter(Mandatory=$true)][string]$fileLocation, #local file which needs to be uploaded to nexus
    [Parameter(Mandatory=$true)][string]$nexusFileName, #display name on Nexus repo
    [Parameter(Mandatory=$true)][string]$nexusDirectory, #Destination in Nexus where the file needs to be stored

#Define Root uri
    "AC"{$nexusRootUri = "https://nexus-acc.alm.<XXXX>.be"}
    "PR"{$nexusRootUri = "https://nexus.alm.<XXXX>.be"}

#Check if repository exists
$repos = Invoke-RestMethod -Method Get -Uri ("{0}/service/rest/v1/repositories" -f $nexusRootUri)
    $encodedCredentials = [System.Convert]::ToBase64String([System.Text.Encoding]::ASCII.GetBytes("$($nexusAccount):$($nexusPassword)"))
    $headers = @{ Authorization = "Basic $encodedCredentials"; "Content-Type" = "multipart/form-data" ; Accept = "application/json" }

    $file = $fileLocation
    $FileContent = get-content($file)

    Add-Type -AssemblyName "System.Web"
    $mimeType = [System.Web.MimeMapping]::GetMimeMapping($file)
    $boundary = [System.Guid]::NewGuid().ToString()
    $nexusApiUri = "{0}/service/rest/v1/" -f $nexusRootUri
    $uploadUri = ("{0}components?repository={1}" -f $nexusApiUri, $nexusRepository)

    $LF = "/r/n"

    Try { $fileBin = [System.IO.File]::ReadAlltext($file) }
		Catch { Throw "Unable to read file $File. Aborted." }
		$bodyLines = (
			"Content-Disposition: form-data; name=`"raw.directory`"",
			"Content-Disposition: form-data; name=`"raw.asset1`"; filename=`"${FileName}`"",
			"Content-Type: application/octet-stream",
			"Content-Disposition: form-data; name=`"raw.asset1.filename`"",
		) -join $LF 
    $objectResponse = Invoke-WebRequest -Method POST -Uri ($uploadUri) -Headers $headers -Body $bodyLines -ContentType "multipart/form-data;boundary=`"$boundary`"" 
    write-error "Repository '$nexusRepository' does not exist!"    
    exit 1


I’d really appreciate any assistance.

Kind Regards,
Devon Britton.
