My original solution:
workaround with $ graphLookup:
@marcobl there are other course takers working on the same labs as you and as a result it’s against forum guidelines to post full or partial solutions to labs. Suggest you delete your post.
There are posts already stating the equivalence between $lookup and $graphLookup under certain conditions. Here’s one such post.
Hi @marcobl,
Your observation and query are correct here. However, I have deleted the queries as it contains answers.
Please feel free to reach out if you have any questions.
Thanks,
