I found out in localstorage of browser there is an installationId which is not JSON object.
So i edit LocalDatastoreController( js file of parse sdk from nodemodule ) : getAllContents (LocalDatastoreController.browser.js:59). i rewrite LDS[key] = JSON.parse(value); with try { LDS[key] = JSON.parse(value); } catch (e) { console.warn('Parse localdatastore warn: key==>' + key+ ', value==>'+ value+ ', error ==>'+ e ) }. to ignore installationId of the device
