Well, Error 105 is Layout is missing. so it looks like this is the line to look at:

$request = $fm->newFindAllCommand('Product');

Couple things I would check:

1) That you spelled the layout name(Product) is spelled correctly (it is case sensitive)

2) if it is, make sure that user has access to it(I think view only wold work).
