It is trying to create a hierarchical block with a variable number of output ports. This functionality is not yet supported. In the past, we silently ignored this, and if the block didn't actually try to use the feature, it would work okay. To be more robust, we recently made this a hard error, which is why the above error message started happening. Looking at the code, it appears that all you need to do is change the line to have an output signature of 1, 1 instead of 1, 2.
