Looks like I have same error: “2023-04-11 08:20:06,396 [http-nio-8080-exec-6 - http://oxnetwiki02:8080/xwiki/bin/get/NestedPagesMigration/Service?outputSyntax=plain&action=printStatusAndLogs&jobAction=createmigrationplan] ERROR o.a.v.d.null - Exception in macro #printStatusAndLogs called at xwiki:NestedPagesMigration.Service[line 16, column 1] " But Nested Pages Migrator Application is on ver. 0.7.5 already and “compute Plan” looks frozen? (I have created separate post Compute Plan does not compute probably not necessary). Also you have mentioned about: “Nested Pages Migrator Application” and “Nested Pages Migrator API”. I cannot find “Nested Pages Migrator API” in the extensions search at all? after some time (usually takes 10 - 20 minutes) browsers reports error: ":8080/xwiki/bin/view…/Migrator/#step-6:1”. Server logs does not report anything at this stage.
