Hello friends
A day ago there was a problem connecting to the company’s network, since then the problem has been fixed but when I try to run my project (trying to run for that matter Trst case) then I get the following error and do nothing: Unable to cast object of type ‘LiteDB.EmptyPage’ to type ‘LiteDB.ExtendPage’.
Does anyone know this and know how to solve the problem? Thank you
Can you please tell where you are getting this…if it is immediately before start only tgen please click open logs and show the execution logs here
If not if it is failing on any activity then open locals panel and show the exception details from locals panel
Cheers

It looks like a logging error …can you try to change system activities package version qnd check
Alternately try to analyze or validate the project and check if there are any errors by opening projects panel and see if there is any red exclamation mark on any of the xamls
Cheers
@Anil_G
There are 2 more XML errors, but even if I solve them, how is this related to the main problem?
Not those…I want you to check the projects panel and see if there are any errors on the xaml file
Did you happen toc hange the package version and check as well?
Cheers
This looks like there is some issue with connecting to the remote server to get the pckages…try to create a new projecta nd check if the issue persists…then please reachout to IT to whitelist the servers to download the pckages
