Picture library slideshow webpart SharePoint 2019 On-Premise

I am using SharePoint 2019 On-Premise. I have created a new picture library. Add some pictures inside of it. After this, I add a picture slideshow webpart on my home page. I selected my picture library and the default view. I got this error:

This library either no longer exists or has no images in it. Please select a different library.

“Why do I got this error? I try also other views, but got the same error. I created a new view and selected it in my slideshow webpart, and got the same error.
In my virtual (VMWare server) workspace works great, but in test server environment i got described error.”

I found similar post here:
Picture library error: This library either no longer exists or has no images in it. Please select a different library
I cannot found any related information in event log.

FYI: I tried upgrade sharepoint to the newest version and not helped me…
I go step by step from this tutorial: https://sharepointmaven.com/add-slideshow-sharepoint-site/ and more others tutorials…
I just found only a small discrepancy in field preview picture(Field Internal Name= “PreviewOnForm”). This field not showing in server environment, it can be error, but I don’t know how to repair it…

How can I query on-premise SQL Server database from Azure SQL database using stored procedure?

I have a Azure SQL database and it has a stored procedure from where I am trying to join a table which resides in on-premise SQL server database.
Essentially, I am trying to query a table which sits in on-premise SQL server’s database.

Are there any options to make cross-server queries from Azure SQL database?

Search result not showing in SP 2019 on-premise modern site to anonymous user

The search result does not show when an anonymous user searches in SP 2019 on-premises modern site. Site is fully anonymous access enabled. I have done this literally 100s of times for classic. And it works for anonymous user if he searches from classic search page but the only problem comes when he searches from modern page.

powerapps forms – Can SharePoint 2019 recognize users thru On-Premise Data Gateway?

We have a SP2019 setup for test purpose. Then we install on-premise data gateway in the environment. We can successfully connect the SharePoint data on-premise to Power Platform. Users can login PowerApps (vai userID@myfirm.com) can read/write/delete the data on-premise thru PowerApps.

However, we see the the “modified by” are the service account (mydomainserviceaccount) we used to setup data gateway. Is it possible SharePoint 2019 can recognize the user who is using PowerApp to update the data?
