Under what scenarios does Dgraph return an array in place of a string?

Users Dgraph
4

This looks odd. It should be like:

		mu.setSetJson({
			'bar': [{'uid': 'uid(bar2)'}], #be careful here, make sure it is ONE to ONE
			'dgraph.type': 'Foo',
		});

As bar is an Edge connecting to another object. This feels like a bug. But for now, fix the syntax to the one I mentioned above.

Do you really need to pass 'dgraph.type': 'Foo' all the time? You should add it in the creation, not in an upsert. But if you are creating it during the upsert, It is fine. Just a small thing, not important.

Line 99

I’m not sure what you are doing in that line. You say “Switch to bar 3” is it a migration of nodes to other references? You should unlink the others if it is a migration.

Fix the syntax there.

Also, if you have a lot of foos foo as var(func: type(Foo)) you will link them all in that upsert. That might be there the issue.

Maybe is the mutation syntax. Check it and let me know.
