ComponentDialog::BuildDialogState throws NullReferenceException
See original GitHub issueVersion
SDK 4.19 .NET 7
Describe the bug
BuildDialogState throws NullReferenceException (in line if (state.DialogStack == null)
Dialog isn’t properly restored in line state = instance.State[PersistedDialogState] as DialogState;, although instance object is set properly, and State seems to be proper JObject. It looks like deserialization goes wrong. Issue appears only after upgrade to 4.19, on 4.18.1 no exception is thrown.
To Reproduce
In my bot:
- Conversation is initiated
- First dialogstack is built
- Response to user is sent.
- User sends message
- On rebuilding stack exception is thrown
Expected behavior
DialogState is properly rebuilt
