Hi there @jvthomas21,
new DB Connectors no longer support plain text passwords. See here for more info and a workaround.
Regarding the Database Type probably it is just wrong value (case sensitive!). To check this add some name (dbtype for example) into the white area next to db_type flow variable while not assigning any flow variable to it. After successful execution there will be a flow variable with above name and real value for database type.
Hope this helps.
Br,
Ivan
