I saw a solution here. But the link just keeps loping back to the link that says "View Original Post" Ouch!

Please Mercy! Mercy! It shouldn't be difficult for this to work I can't understand why that error woudl be there when the App Checker says it's all good.

Thanks in advance for your help.

The two solutions I followed to create , New, Edit, View Pages in PowerApp ( Teh second one has typos and copying and pasting the quotes require you to retype the quotes)

Hi @MikeRooker ,

Have you published your custom form app to your SP List properly?

Based on the issue that you mentioned, I have made a test on my side, and don't have the issue that you mentioned. Please make sure you have published your custom form app to your SP List properly.

Also please consider clear cache of your browser, then sign in your SharePoint List again, then check if the issue is solved. Edit your custom form app, add the following formula within the OnNew property of SharePointIntegration control:

Refresh('Your SP List'); // Add this formula Set(SharePointFormMode, "CreateForm"); NewForm(CreateItemForm); Navigate(CreateScreen, ScreenTransition.None)

set the OnEdit property of SharePointIntegration control:

Refresh('Your SP List'); // Add this formula Set(SharePointFormMode, "EditForm"); EditForm(EditItemForm); Navigate(EditScreen, ScreenTransition.None)

Set the OnView property of SharePointIntegration control to following:

Refresh('Your SP List'); // Add this formula Set(SharePointFormMode, "ShowForm"); ViewForm(ShowItemForm); Navigate(ShowScreen, ScreenTransition.None)

then save your canvas app, and re-publish it to your SharePoint List, check if the issue is solved.

Best regards,

Hello @v-xida-msft , thank you for your reply.
Yes Sir, I definitely published correctly. 😞
I have cleared my cache and also have tried it on, Firefox, Edge and of curse IE. 😞
Oddly enough, I had noticed that even "duplicating" or adding a screen and saving it; that alone is enough to render the PowerApp with an error.

I followed your kind instructions as follows and had renamed the items accordingly.

OnNew

OnEdit

OnView

Wow I can't understand why this wouldn't work.
I am so very grateful for your assistance.
I have bee stuck with this for a week now.

Thank you kindly.

Hello again @v-xida-msft , I found something even more disturbing and may add a clue,
After resetting to the SharePoint Form, all goes well.
But if I make even the slightest change, such as hide a field, or create a screen and save. It will error.
Is there something perhaps wrong at the tenant where they toggled something of sorts that's causing issues?

Thank you again!

Hi @MikeRooker ,

Currently, I could not reproduce your issue on my side. Have you taken a try to launch your SP List custom form app within another PC, same issue occurs?

Please take a try to run your custom form app in another PC, then check if same issue occurs. Have you taken a try to remove your custom form app and then re-create it again?

I think this issue may be related to updates in PowerApps. Please consider remove your custom form app from your SP List, then re-create a new one for it, check if the issue is solved.

If the issue still exists, please submit an assisted support ticket along with the Session ID of your custom form app for further help through the following link:

https://powerapps.microsoft.com/en-us/support/pro

More details about capturing Session ID of a canvas app, please check the following article:

Yes unfortunately.

Yes, I have tried that as well and the same results.

Thank you so much I out a ticket in and he was able to reproduce the issue( I think he's a third party solution MS uses ). He tried to find a quick fix for a form field instead of the application it self and then told me that he couldn't reproduce it on his machine and tried to use that a way to end the ticket and I said yes it works fine on my own personal tenant but not on the tenant with the issue. ?? Anyhow he elevated the issue saying that my app does not "save as" and becasue of it , it won't work. But waiting for more info.
Thank you again.
