OK, that node pulls in a lot of dependencies which means that npm will end up using a lot of memory, potentially more than the amount assigned to your instance which means it will get killed by the hosting system.
A quick fix will be to suspend the instance and then restart it. As the instance starts up it should install the node before starting Node-RED and hence not hitting the limit. The node should have been added to the list of used nodes, but if not you can add it in the instance settings.
The other option is to move to the larger instance types, but that will incur a cost as only a single small instance is included in the free trial.
I think you are right. Oddly when restarting I get different behavior from completely stopping and starting.
Restarting it would never start. Stopping and starting caused a boot loop. I will remove this palette and do this test locally.
