Upsert query variables fails #4286
Description
Working Upsert
const query = `
query {
user as q(func: eq(user.id, "${request.userId}"))
}
`;
const mu = new dgraph.Mutation();
mu.setDelNquads(`uid(user) * * .`);
const req = new dgraph.Request();
req.setQuery(query);
req.setMutationsList([mu]);
req.setCommitNow(true);
const res = await dgraphClient.newTxn().doRequest(req);
When directly inserting the value of request.userId into the query string via string interpolation, the node returned by the query is successfully deleted.
Failing upsert
const query = `
query q($userId: string) {
user as q(func: eq(user.id, $userId))
}
`;
const mu = new dgraph.Mutation();
mu.setDelNquads(`uid(user) * * .`);
const req = new dgraph.Request();
const vars = req.getVarsMap();
vars.set("$userId", `${request.userId}`);
req.setQuery(query);
req.setMutationsList([mu]);
req.setCommitNow(true);
const res = await dgraphClient.newTxn().doRequest(req);
When trying to use query variables and setting the corresponding entry in the variables map for $userId with `${request.userId}`, the node that should be returned by the query is not successfully deleted.
Is this an unsupported feature for upserts or is something wrong with the code?
