There is a bug or incorrect information in the GDS Product Introduction Course in the Graph Academy.
Both the "targetNode" and "dataConfig" node have the same definition. I am not sure if it is suppose to be the same, but I believe it should be different.
Thank you for taking a look
There is also incorrect cypher query this page:
The create projection is 'cypher-proj' but in the following query it is refereed to as 'proj-cypher'. I have attached a screenshot in a comment.
