An error occurred in one of afterSave callbacks DataCloneError: Failed to execute ‘postMessage’ on ‘DedicatedWorkerGlobalScope’: # could not be cloned.
That´s the error message that I suddenly get and I have no idea where it occurs and why.
Before this one, in the browser´s console this one comes up also:
SiteAspectsSiteAPI.js:63 Uncaught TypeError: Cannot read property ‘getPageOfComp’ of undefined
at o.getRootOfComponentId (SiteAspectsSiteAPI.js:63)
at o.e [as getRootOfComponentId] (lodash.min.js:46)
at o.getComponentById (SiteAspectsSiteAPI.js:38)

at dataCapsuleWrapper.js:7
at r (frame-storage-listener.js:43)
at MessagePort.e.onmessage (listen-factory.js:30)
Editor:
Can anyone help me out here?
EDIT: found it. postMessage choked on messaging an unfullfilled Promise.
