javascript - How to handle this Firebase error -


i error seems should handled don't know how because error happening on firebase sdk

app.js:35774 uncaught (in promise) error: disconnect @ repo_1.repo.reruntransactionqueue_ (app.js:35774) @ repo_1.repo.reruntransactions_ (app.js:35686) @ object.<anonymous> (chat.js:35666) @ persistentconnection.cancelsenttransactions_ (app.js:33032) @ persistentconnection.onrealtimedisconnect_ (app.js:32911) @ connection.close (app.js:32266) @ connection.onconnectionlost_ (app.js:32232) @ websocketconnection.<anonymous> (app.js:31964) @ websocketconnection.onclosed_ (app.js:31647) @ websocket.mysock.onclose (app.js:31504) 

it happens during disconnection event. have transaction code might connected error, although i'm not sure why might causing error:

var timeupdate = 300  firebaseapp.ref.child('sessions')   .child('sid')   .child('time_on')   .transaction((v) => {     return v + timeupdate   })
