Android Question DropboxHttpAPI -- Error on new device

[GaryK4]

I have a simple program that copies a file from my dropbox to the download folder.
When I tried to make changes to if, I can no longer get it to work and the debugger does not help.

dbx.Initialize(Me,"DropBox","access_token",True)
    Try
        If dbx.IsInitialized Then
            dbx.Download("/hdcp_index.txt",File.DirRootExternal,"Download/hdcp_index.txt")
        Else
            Msgbox("Dropbox was not initialized","Error")
        End If
    
   Catch
        Log(LastException)
    End Try

When I hit the download line, I get the following error. Try/Catch does not work.
I'm not sure what to do next?
DropboxHttpAPI v 0.93
Note 8

I guess you are using the compiled class as library.
Same issue as here is guess.

Or you just did forget to check the okhttputils2 library in your new project.

I am using the library and yes it is the same problem.
I downloaded the source and recompiled the library.
That fixed the error. All is good again.

Thanks,
Happy New Year.
