"Uncaught (in promise) TypeError: Cannot read property 'emit' of null"

[vidjuheffex]

when I call the setState in a subsequent useEffect call I get this.

Seems to work, but the next call is not valid.

I got the same error sometimes. Waiting for a workaround

@szotyi41 I used this to work around the bug:

  //Wallet State
  const [persistedWallet,setPersistedWallet] = createPersistedState("wallet")({wallet: "Chainweaver"});
  const [walletProvider,setWalletProvider] = useState(persistedWallet);
  // Experimental wrapper for "emit" bug found in https://github.com/donavon/use-persisted-state/issues/56
  useEffect(()=>setPersistedWallet(walletProvider),[persistedWallet, walletProvider, setPersistedWallet]);

I'm experiencing this issue as well. It only happens with prod builds and not during dev.

Temporary workaround is to wrap set setState function inside a try/catch block.

Same happens to me when I setState inside a useEffect hook

[garrettmaring]

is it possible that this was a regression? i've only just started experiencing this

Seeing this as well in development when I create multiple persisted states on multiple pages, all with different keys.

"use-persisted-state": "^0.3.3"

EDIT: Because of #36, I am using https://www.npmjs.com/package/use-local-storage-state now. It works.
