MismatchedInputException: No content to map due to end-of-input #9

Hi, I'm one of the developers interested in Federated Learning, thus I've been trying to run your Photolabeller example.

While trying to run the server, I'm faced with an error that I cannot figure out the reason.

I succeed to run the Main.kt file by providing arguments to the function and it successfully saved the result.

Then, I tried to run the Federated Learning server by executing the JobQueueServer. The server was successfully started as shown in the screenshot.

However, when I tried to check that the server is up and running in your local installation by hitting the suggested URL http://localhost:9997/service/federatedservice/available, I got the following error.
