Description

This doesn't seem to affect functionality

 

There are 2 distinct errors in the console when starting/stopping process groups either from the operation control or the context menu:

ERROR TypeError: Cannot read properties of undefined (reading 'canRead')
    at OperationControl.getContextName (operation-control.component.ts:134:40)
    at OperationControl_ng_container_6_div_1_Template (operation-control.component.html:38:61)
    at executeTemplate (core.mjs:12003:13)
    at refreshView (core.mjs:13498:13)

ERROR TypeError: Cannot read properties of undefined (reading 'canRead')
    at SVGRectElement.<anonymous> (process-group-manager.service.ts:204:34)
    at SVGRectElement.<anonymous> (classed.js:58:12)
    at Selection.__WEBPACK_DEFAULT_EXPORT__ [as each] (each.js:5:37)
    at Selection.__WEBPACK_DEFAULT_EXPORT__ [as classed] (classed.js:71:15)
    at ProcessGroupManager.updateProcessGroups (process-group-manager.service.ts:203:39)
    at ProcessGroupManager.set (process-group-manager.service.ts:1368:14)
    at Object.next (process-group-manager.service.ts:1326:22)
    at ConsumerObserver.next (Subscriber.js:91:33)
    at SafeSubscriber._next (Subscriber.js:60:26)
    at SafeSubscriber.next (Subscriber.js:31:18)

 

Both appear related to the reducer assuming the response of the api call returns the whole object with `permissions` and such. in the case of process groups, it is a very sparse return object and doesn't have those.

 

We should be sure the "fix" works for all startable/stoppable components.
