I'm encountering the following error when attempting to open a project I forked via GitHub.
success open and validate gatsby-configs - 0.492s
 ERROR #11331  PLUGIN
Invalid plugin options for "gatsby-source-contentful":
- "accessToken" is required
not finished load plugins - 6.220s
I've made several edits but am unable to work on the project as I'm unable to open it at the moment.  I do have a contentful account, but am fairly new to Gatsby and am unaware of how to set a new value for the accessToken.
Would I need to do this via process.env, or am I missing the process entirely?
Thank you, any help is appreciated.
