Error: Exit code 1
     Uh oh, an unexpected exception brought the process down! That should never happen. Please file a bug report.

     Here's a stringy rendering of the exception:

       SqliteQueryException {sql = "SELECT version FROM schema_version", params = [], exception = SQLite3 returned ErrorError while attempting to perform prepare "SELECT version
     FROM schema_version": no such table: schema_version, callStack = [("throwSqliteQueryException",SrcLoc {srcLocPackage = "unison-sqlite-0.0.0-G7Hvma1jWfnDrEtoviTZTM",
     srcLocModule = "Unison.Sqlite.Connection", srcLocFile = "src/Unison/Sqlite/Connection.hs", srcLocStartLine = 252, srcLocStartCol = 9, srcLocEndLine = 252, srcLocEndCol =

     = Connection { name = "main", file = ".unison/.unison/v2/unison.sqlite3" }, threadId = ThreadId 14}

     And here's a different one, in case it's easier to understand:
