what-if tool unable to return predictions - InactiveRpcError

[mollie9523]

hello, i am running a simple classification problem (uci census, using the pre-trained model and dataset from the tensorboard what-if guide; test set/model direct link).

i am currently using docker with tf serving to serve my model. i have inputted the localhost:8500, signature as 'classification'. however, i am getting the following error. i am able to load the datapoints properly as well. is there anything that i need to modify or?
