Answer 1

When running some code with the #Scheduled Annotation you need to define the context. Otherwise you get this exception, as the thread using a cumulocity API is not within any context.
E.g. for all subscribed tenants:
private final MicroserviceSubscriptionsService subscriptions;
#Scheduled(fixedDelay = 5 * 60 * 1000)
private void checkForAgentRepresentation() {
for (final MicroserviceCredentials mc : subscriptions.getAll()) {
final String tenant = mc.getTenant();
subscriptions.runForTenant(tenant, () -> {
//doSomething like
inventoryApi.get(...);
});
}
}
