Hi!
I’m encountering the following error:

Message: Cannot create unknown type ‘{http://schemas.microsoft.com/netfx/2009/xaml/activities}Variable({http://schemas.uipath.com/workflow/activities}DatabaseConnection)’.

Exception Type: System.Xaml.XamlObjectWriterException

I’m using an activity (DatabaseConnect) to connect to a Database. Weirdly enough, the Connection Wizard works perfectly, and I was able to attest that the connection to the Database can be estabilished. However, whenever I run my workflow, I get this error.

I’m working with a computer that doesn’t have internet connection, so I had to install the database package through Manage packages>Settings>Add.
From what I’ve seen in other threads, maybe the files from this package hadn’t been installed correctly, but the connection can be estabilished, and I found 3 files from this package in C:\Users<USER>\AppData\Local\UiPath.cache
The files are:
UiPath.Database.Activities.Design-v1.3-25187d4f.Reflection.dat
UiPath.Database.Activities-v1.3-fbdf0bf2.Reflection.dat
UiPath.Database-v1.3-8e291670.Reflection.dat

Am I missing anything?
Thanks!

I too just recently started to see and log this error with some of our users.
Any ideas to the cause. I have some users running the exact same process, but are not getting this error, so only happening on a few, not all.
This is a local (RDA) process.
