// "Orchestrator functions should never use any input or output bindings other than the orchestration trigger binding.
// Doing so has the potential to cause problems with the Durable Task extension because those bindings may not obey the single-threading and I/O rules."
//
// Therefore, it's by design that 'InputData' contains only one item, which is the metadata of the orchestration context.
