What does this implement/fix? Explain your changes.

"extraData" expects a string but receives an array or object. This bugfix JSON encodes an array so a string is returned.

Does this close any currently open issues?

This might also fix issue 437. I had the same error locally and it's solved.

Any relevant logs, error output, GraphiQL screenshots, etc?
