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 Value: Condition vCheckedOut is equal to true Yes: Do until vCheckout is equal to False GetFileProperties Set variable Name: vCheckedOut Value: Checked out (value from the Get file properties above) No: Set variable Name: vFolderPath Value: FolderPath (SharePoint field)
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
Error I was receiving: System.MissingMethodException: Method not found: ‘System.Runtime.Remoting.ObjectHandle System.Activator.CreateInstance(System.String, System.String)’.
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:
Open the Command Palette on Windows or Linux with Ctrl+Shift+P. On macOS, use Cmd+Shift+P.
Search for Session.
Click on PowerShell: Show Session Menu.
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.
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: https://docs.microsoft.com/en-us/sharepoint/dev/solution-guidance/security-apponly-azureacs You can create an app principle that is limited to a single site, list, library, or a combination of them: https://piyushksingh.com/2018/12/26/register-app-in-sharepoint/
In this example, I’m connecting to a Site Collection on my tenant.
1) You have created a token in your o365 site
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
