Scalar must read single field

in the Deferred transactions at https://docs.microsoft.com/en-us/dotnet/standard/data/sqlite/transactions#deferred-transactions the statement reads
readCommand.CommandText =
@"
SELECT *
FROM data
";
whereas [because intended to fetch exactly one field] it should read
readCommand.CommandText =
@"
SELECT value
FROM data
";
