Getting this error when trying to sign a transaction , so after creating a tx its waiting in pending signature state.

So when i get a TransactionStatus of a tx as PENDING\_SIGNATURE i sign that tx … but its giving the private key not found error

```auto
      if (TransactionStatus.PENDING_SIGNATURE) {
        await sdk?.signTransaction(txId);
      }

```

Got the solution for it … so i was using  
`const secureStorageProvider = new InMemorySecureStorageProvider();`

but it didnt work, instead this one worked  
`const secureStorageProvider = new PasswordEncryptedLocalStorage`
