Syncing has unexpected type about y-indexeddb

[eberberich]

Removing this line, removes the error, but also the persistency

const ydocIndexeddbProvider = new IndexeddbPersistence(docName, ydoc);

Unable to reproduce

It is this function that throws

export const findRootTypeKey = type => {
  // @ts-ignore _y must be defined, otherwise unexpected case
  for (const [key, value] of type.doc.share.entries()) {
    if (value === type) {
      return key
    }
  }
  throw error.unexpectedCase()
}

Can you explain how the === may not be met? - in particular in light of using a Y.Array on JS (proxy [vue]) objects

The test contains some kind of recursion: value is a value of the map type.doc.share.entries(), which howeve is compared against type - but the mentioned map comes from a nested field of type

More info: It happens when the syncing from IndexedDB is still in progress and we already access somewhere else yDoc.getArray("events")

EDIT: If i wait with calling yDoc.getArray("events") until ydocIndexeddbProvider.on('synced') has been called, the error disappears! For example by using a promise and resolving it in the on-synced callback - and (only) then (i.e. upon then) calling the getArray
