Hi Sundar,
I've checked our logs and there is a mandatory datasetIds parameter that is not being sent by the Beacon Network, which is causing queries to the EVA beacon to have error responses. We have no dataset names in our database for the EVA beacon.
If you can provide us with a functioning query we can use to update our database records for the EVA beacon, we would be happy to resolve this issue.
Cheers,
Max Barkley
