"Perfom Training" Action on a ML Project with model type Order Route is throwing error

"Perfom Training" Action on a ML Project with model type Order Route is throwing error "Failed at parsing training input: Input data for training is empty. Ensure the data is loaded into analytics. Also, check if the data exists after applying the filters.". This error shows up even after loading related order data successfully into Analytics. The similar setup when done on ML project with model type Shipment ETA, it works successfully and trains the model

Has anyone else faced this error Training with Order Route model in OTM?

Thanks in advance!!
