Looking at the docs:
https://dgraph.io/docs/query-language/graphql-variables/
It does show how to query a list of uids using the “graphql variables” (most horrific naming still).
But is there yet a way to do this quoted array with a list of something other than uids? I don’t believe so. So I have to expand my variable list passing each variable as it’s own named variable. Not very user friendly for sure.
Yeah, it seems that naming convention: “GraphQL Variable” is a relic for sure. I would think a more appropriate name would be something like “DQL Parameterized Variables”.
I checked out the parser for this in the code and it seems the only supported values for the array signature are UIDs. Here’s a GH issue to track: DQL variables don't seem to be supported in arrays · Issue #2272 · dgraph-io/dgraph · GitHub
