Internal Server Error by queryByShape()

[Camden Daily]

Have you tried simply drawing your shape on the map to make sure it's
what you think it should be?  Your 'for' loop looks like it may have
an 'off by 1' error, as you start at 0, and then check for less than
your array size -1.  With that loop, you'll never hit the very last
element in the arXCoords array.  Since I believe a polygon shape
should have the first and last points being the same (to close it up),
your shape may not be getting properly closed.

Just a thought.
