PowerApps Custom Form Not Working After Site Replication in SharePoint Online

(0) Share

Report

Posted on by PattiFszg52

I am working with a SharePoint Online site named PMTemplate, which contains various lists, libraries, and custom pages. One of these lists, the Project List, has a custom form created with PowerApps. I used PnP PowerShell to replicate this site to a new one, and while most of the lists, libraries, and views were successfully copied, I encountered issues with the PowerApps custom form.

Problem:

After replicating the site to the new SharePoint site, the PowerApps custom form for the Project List does not open when adding a new item.
In List Settings → Form Settings, the option "Use a custom form created in PowerApps" is disabled, while only the default SharePoint form option is enabled.
When I click on "Customize in PowerApps", I can open and modify the form in PowerApps. However, after updating the data source to the new site’s Project List, clicking "Back to SharePoint" takes me to the old site, not the new one.

Now, How can I enable the "Use a custom form created in PowerApps" option in the new site? and How can I fix the redirection issue when clicking Back to SharePoint?

Any Help Would Be Appreciated!

Hi,

I hope this is most common issue which we faced if we clone / copy the site in sharepoint.

Open PowerApps → Customize the form click on Save and publish and Now check the customize form will be available.

Set-PnPList -Identity "SharePoint List Name" -DefaultDisplayFormUrl "/sites/Site Name/List Name/Forms/PowerApps.aspx"

Redirection Issue (Update the SharePoint Integration Property) Launch URL with respective to the new application

Hope this helps!

Hi @MS.R-08012015,

Thank you for your response i have tried first two options.

I opened the Power Apps customization form and then i save and published the form. After i refreshed my new SharePoint site, when i click on + Add new item it is still opening SharePoint default form not the Power Apps custom form.

Then, i run the PnP Power Shell command by connecting to my SharePoint site. Then i got the below error.

The third option: Update the SharePoint Integration Property - can you please explain where i need to update this property.

Hi PattiFszg52,

Connect-PnPOnline -Url "https://your-new-site.sharepoint.com/sites/NewSite" -UseWebLogin

Get-PnPContentType -List "Your List Name"

Set-PnPContentType -List "Your List Name" -Identity "0x0100..." -DisplayFormUrl https://apps.powerapps.com/play/environment-id/app-id

If DisplayFormUrl Doesn’t work

Set-PnPList -Identity "Your List Name" -FormCustomFormUrl "https://apps.powerapps.com/play/environment-id/app-id"

Replace "https://apps.powerapps.com/play/environment-id/app-id" with your PowerApps form link.
