The VkGraphicsPipelineCreateInfo is very complex and narrowing down the issue would make it easier to track down the error.  In this case, I wasn't setting the pVertexInputState structure fields, leaving the values null.  So adding something like \"pVertexInputState.pVertexInputState  must not be null\" would have pointed me in the right direction."}}
