I have created a custom adapter for reading AIS data in Denmark, the source code is available on GitHub:
The adapter is implemented for GeoEvent 10.2.0 and I've been running it successfully for a couple of months.
This week I've been trying to install it on a 10.2.2 server, and I receive the following error:
Invalid stream configuration: stream name is required.

I can create a connector using the AIS adapter, the error appears when I try to add a new Input. Screenshot:
I've tried to raise the log level, with no success.

What can I do to dig deeper and find the cause of this error?
