Error 1329 even with continue handler and rows returned

[Josh Higham]

This has me pretty confused. I've done a lot of searching about the error, I have the continue handler set correctly, and I've reduced the procedure down to bare bones and confirmed that it is in fact selecting data in the cursor (and then displaying it).

However, I still get the error 1329.
