Description:

Script error when accessing a document created by ProseMirror example on dashboard

After creating the document of the ProseMirror example of the JS SDK, there seems to be a script error occurring when accessing the document on the Dashboard.

In the example, the selection is saved as a byte array type in the document to propagate it to the peers.

However, this seems to be causing a script error when performing JSON.parse on the Dashboard.

Why:

can I try this?

@DongjaJ Sure.

The error occurs when assigning a byte array(Uint8Array) to a document.

I found the following error in the process of re-creating this issue.

1. create the document of the ProseMirror example of the JS SDK
2. access the document on the Dashboard
3. click another tab (ex. Project overview, api, setting...)

And I could not recreate Error on this issue

We have stabilized yorkie.Tree until the v0.4.7 release. For now, the error described in this issue does not recur for now.

For #130 (comment):
I have confirmed that the issue described in the comment still occurs in development mode. This is only happening in the development environment, so I guess it is related to the development mode.
