TypeError: prevDeps is undefinded, when editing content

Description

After adding the TinaCMS in my existing Gatsby site, I’m receiving a error message when editing my content both in TinaCMS sidebar and directly in my markdown files. When I remove TinaCMS dependencies the error does not occurs anymore.

The error says the following:

TypeError: prevDeps is undefinded 

Steps to reproduce

• install tina-cms to my existing gatsby project
• setup it in gatsby-config.js
• run a development server with the gatsby develop command
• access http://localhot:8000/ in my browser.
• edit a content in the tina sidebar

Expected result

Edit the content without errors.

Actual result

After editing the content a error message is shown.
