Hello,
we see an error in our logs when creating new pages using Page Tree Creator Pro templates:
ERROR [http-nio-8090-exec-18 url: /rest/treecreator/1.0/completed/f9d7fd36-8683-4692-8c90-03cd5908dc93; user: XXX] [common.error.jersey.ThrowableExceptionMapper] toResponse Uncaught exception thrown by REST service: service matching filter=[(objectClass=com.atlassian.confluence.setup.settings.GlobalSettingsManager)] unavailable
-- referer: | url: /rest/treecreator/1.0/completed/f9d7fd36-8683-4692-8c90-03cd5908dc93 | traceId: 4c193a83e2ae2c09 | userName: XXX
org.eclipse.gemini.blueprint.service.ServiceUnavailableException: service matching filter=[(objectClass=com.atlassian.confluence.setup.settings.GlobalSettingsManager)] unavailable
The creation pop up doesn't disappear until you close it, after some minutes an error appears on the right:

When you close the window, the desired page is created, even though the error appears.
We already restarted Confluence and cleared the plguin cache.
Has anyone seen this error before? I´ve also reached out to the Page Tree Creator support, as I am not sure what the cause of the problem is.
