Hi everyone
My OpenHIM-Core version is 3.4.0 and in the server log there is no error

[ryan]

Hi Sabri,

Richard has been keeping me up to date with your troubleshooting. I’m wondering if that message you are getting just meant that the there is not mediator config for the mediator so it’s getting back blank JSON. It may be fine to ignore this message. If you click on the mediators tab on the OpenHIM does it show that the mediator is stays running even after this error?

The Java mediator isn’t often used, more commonly the Javascript mediators are used so I don’t recall all the nuances of creating a Java mediator.

It seems that you are able to send requests to the mediator just fine, so perhaps this is working as expected?

Cheers,

Ryan
