More recent research has determined the real author is Johann Christoph Bach (1642-1703) -Bach of Eisenach- (not J. S. Bach's uncle -named the same- but Heinrich's son: a very inspired cousin of his father).
So, it should be corrected.
Also, the work "Wie bist du denn, o Gott" is correctly attributed to the same author (Johann Christoph Bach), but the dates of birth and death are erroneously those of the other Johann Christoph Bach (1645-1695), Johann Sebastian Bach's uncle, twin brother of his father Johann Ambrosius, who died only a few weeks later.
A very common mistake.
