I'm getting an error that the block mapper has exceeded the maximum search time. My response is only 7 lines long and I only have 2 blocks in the root container. The first is an optional line (which is the first of the 7 lines) the second block is a pair of lines that is repeated 3 times in the response.
I have no idea why it is timing out. I added this response to the samples for this response map and it maps fine there.
