The error message is pretty much self explanatory:
[SQLITE_ERROR] SQL error or missing database (no such table: githublists)
It's telling you as clearly as it can that you have asked it to INSERT data into a table called "githublists" and that table does not exist in that file.
Check your SqLite database file - make sure it's the one listed in the connection string - and pay attention to the table names: did you call it "githublist" or "githublists" for example.
And don't "hard code" connection strings into you app - always use a config file as otherwise you have to release untested software once you change the location for release versions.
