invocation of amazon.nova-pro-v1:0 didn't work

Hi, I ran the notebook "01_Getting Started with Nova Models" from workshop in multimodal-understanding, I got an error of "Invocation of model ID amazon.nova-pro-v1:0 with on-demand throughput isn't supported." Is there a way to fix this? or do I need to switch to "provisioned throughput" to actually test the code at this time. Kindly advise. thanks for your help.
