Flow Power Automate and SharePoint Required Fields

On the surface, this request sounded super simple and straightforward. “we need to copy files from a SharePoint library to Blob storage.” Simple enough? Well, yes, but the SharePoint library has a couple of required fields and a Flow is triggered by an action.

Consider what I’m outlining below to be version ONE of the process. In the near future, I will update this post with a slightly more resilient solution.

My SharePoint library has a required field titled DesinationFolder

Context of what I’m doing in the Flow:
Trigger: When files is created in a folder
When a file is added to a library the flow is triggered
Get file metadata
File Identifier: Use File identifier from the step above
Get file properties
Id: Use the ItemId from the previous step
Initialize variable
Name: vCheckedOut
Type: Boolean
Value: Checked out (field from Get properties)
Initialize variable
Name: vFolderPath
Type: String
vCheckedOut is equal to true
Do until
vCheckout is equal to False
Set variable
Name: vCheckedOut
Value: Checked out (value from the Get file properties above)
Set variable
Name: vFolderPath
Value: FolderPath (SharePoint field)

/blobfolder/vFolderPath (variable)
Create blob

Get-PnPSearchCrawlLog Filter to a List or Library

Using the Get-PnpSearchCrawlLog cmdlet wanted to filter the returned result set to a specific list. Before you begin, you’ll want to make sure you have access to the Crawl Log: https://yourSite-admin.sharepoint.com/_layouts/15/searchadmin/crawllogreadpermission.aspx

Connect-PnPOnline -Url "https://sharepointed.sharepoint.com/sites/food" -Credentials (Get-Credential)

$logs = Get-PnPSearchCrawlLog  -filter "https://sharepointed.sharepoint.com/sites/food/Lists/tacos/"

foreach($l in $logs)
    Write-Host "    "
    Write-Host $l.Url
    Write-Host $l.ItemId
    Write-Host $l.LogLevel
    Write-Host $l.CrawlTime

This will filter the returned results to a specific list. Note: when using Connect-PnPOnline I use my email address and App Password. App Password can be created/found here: https://account.activedirectory.windowsazure.com/AppPasswords.aspx

System.MissingMethodException: Method not found Connect-PnPOnline

Using Visual Studio Code and SharePoint PNP I was trying to make some updates to a list but I wasn’t able to connect to a site.

Connect-PnPOnline -Url "https://taco.sharepoint.com/" -Credentials $creds

Error I was receiving:
System.MissingMethodException: Method not found: ‘System.Runtime.Remoting.ObjectHandle System.Activator.CreateInstance(System.String, System.String)’. at SharePointPnP.PowerShell.Commands.Base.ConnectOnline.ProcessRecord() at System.Management.Automation.CommandProcessor.ProcessRecord()

I tried uninstalling VScode, removed all traces of SharePoint from my laptop, and cleared the GAC. Nothing worked.

Here is what did work:
In VScode:

  1. Open the Command Palette on Windows or Linux with Ctrl+Shift+P. On macOS, use Cmd+Shift+P.
  2. Search for Session.
  3. Click on PowerShell: Show Session Menu.
  4. Choose one of the ___ (x86) options

Not sure how, but I was using an x64 session and SharePoint PNP clearly didn’t like that.

Edit: Updated VScode to the latest version and it managed to reset my session settings. When this happened, it caused my CSOM scripts to report a The remote server returned an error: (400) Bad Request error. The fix above will resolve the error.

Connect to SharePoint Online Using PowerShell

Update and a much better way to approach this:
Use a SharePoint App Only Client Id and Secret to access the site, list, or library.

Microsoft documentation:
You can create an app principle that is limited to a single site, list, library, or a combination of them:

 $sampleConnect = Connect-PnPOnline -Url "https://YOURsite.sharepoint.com/sites/parent/child" -AppId "12345-94c3-4149-bda5-abcedffadsf" -AppSecret "643r4er5sfdadsfadsfdsf=" -ReturnConnection

Write-Host  $sampleConnect.Url
In this example, I’m connecting to a Site Collection on my tenant.

1) You have created a token in your o365 site
1.1) https://portal.office.com/account/
1.2) On the left site of the page click Security & privacy, then click Create and manage app passwords
1.3) In the app password page click the create button and give it a name.
1.4) Save the password to a secure location.
1.5) There is a better way of doing this that I will cover in a future post.
2) You have downloaded to CSOM DLL(s) from Nuget


$userName = "me@sharepointed.com"
$pw = "abc123taco"  # I"M USING AN APP PASSWORD 
$siteCollectionUrl = "https://sharepointed.sharepoint.com/sites/taco"

#Secure the password
$securePassword = ConvertTo-SecureString $pw -AsPlainText -Force

Add-Type -Path "C:\Code\DLL\Microsoft.SharePoint.Client.dll"
Add-Type -Path "C:\Code\DLL\Microsoft.SharePoint.Client.Runtime.dll"

#Create Context
$ctx = New-Object Microsoft.SharePoint.Client.ClientContext($siteCollectionUrl)

$ctx.Credentials = New-Object Microsoft.SharePoint.Client.SharePointOnlineCredentials($userName, $securePassword)

$web = $ctx.Web
$properties = $web.AllProperties

Write-Host " Site Collectione URL: $($web.Url)"
Write-Host "Properties are "

foreach ($prop in $properties) {
