28.02.2019 12:46:00.026 *WARN* [127.0.0.1  GET /api/screens-dcc/devices/stati HTTP/1.1] com.adobe.granite.rest.impl.ResourceAdapterFactory Unable to handle adaptable com.adobe.cq.screens.impl.rest.DevicesStatiResource
Hi, does someone know how to get rid of this message?
I believe the WARN message is displayed as soon as a screens replication agent is enabled and polling from author to publish begins. This seems to be a minor bug which is being reported to AEM Engineering already and is being worked upon.
If you're seeing a lot of them you can probably route them to a different log file by creating a separate logger to avoid clutter in the main log file.
If Screens is not being used, a work around is to change the Author to Publish polling schedule so it occurs very infrequently. Create an OSGI Configuration on com.adobe.cq.screens.impl.jobs.DistributedDevicesStatiUpdateJob that changes the schedule to something like 0 0 1 1 * ? - which would amount to once a year on January 1st.
This workaround will just silence this message:
Set the loglevel for the class "com.adobe.granite.rest.impl.ResourceAdapterFactory" to ERROR.
That warning can be ignored. It's going to be fixed with a recent SP of AEM 6.4 (maybe already included in 6.4.3, haven't checked).
Can confirm this is still an issue in AEM 6.4.3 (still have to check with 6.4.4). Thanks for the workaround though, we'll implement that in the meantime
