Leipzig, 1736; NBA No. 20.
The melody is not by J.S. Bach and there is very little evidence that Bach had anything at all to do with the figured bass line.
Use of the Chorale Melody by other composers:
Ulrich Hildebrandt (1870-1940): O du Liebe meiner Liebe, choral for organ
Georg Scheel (1866-1945): O du Liebe meiner Liebe, choral prelude for organ
Sources: NBA, vols. III/2.1 & 2.2 in particular [Bärenreiter, 1954 to present] and the BWV ("Bach Werke Verzeichnis") [Breitkopf & Härtel, 1998]
