@bocanegra Not sure if you already found a solution, but I was experiencing the same issue trying to build what is essentially the animate elements from the official documentation The only major difference is that I am running the chart.add_rows in a separate thread. The solution for me was to call thread.join() after creating my thread and adding the report context. Credits for the solution go to tim.
thread = threading.Thread(target=my_func, args=my_args)
thread = add_report_ctx(thread)
thread.start()
thread.join()
