SQLLite error when running Command Line built from source

Hi,

I am running a simple backup job:
Duplicati.CommandLine.exe backup C:\backup C:\data\hello.txt

When I run it with the Windows package, things work fine. When I build and run from source (compiled in Visual Studio), I get the following error (after providing the password):

2019-05-22 11:55:18 -07 - [Error-Duplicati.Library.SQLiteHelper.SQLiteLoader-FailedToLoadConnectionSQLite]: Failed to load connection.
System.IO.FileNotFoundException: The system cannot find the file specified. (Exception from HRESULT: 0x80070002)

at Duplicati.Library.SQLiteHelper.SQLiteLoader.LoadConnection() in C:\Users\me\duplicati-master\Duplicati\Library\SQLiteHelper\SQLiteLoader.cs:line 109

Any idea what I need to do here? Specifying a dbpath doesn’t seem to help.
