Help! shortestpath Query Structure?

Thank you for the reply, Michel.

A1: All the links seem to work well and I can execute the query perfectly between individual Skill and Resource nodes (see code block):

{

   S as var(func: eq(XID, "Skill/NAICS/54"))
   R1 as var(func: eq(XID, "Resource/bob/smith"))

   path as shortest(from: uid(S), to: uid(R1), numpaths: 1) {
      Skill.Skills @facets(resistance)
      Skill.Organizations @facets(resistance)
      Skill.Resources @facets(resistance)
      Organization.Projects @facets(resistance)
      Project.ProjectRoles @facets(resistance)
      ProjectRole.Resource @facets(resistance)
    }
  
  path(func: uid(path)) {
   dgraph.type
   Name
   XID
  }
}

A2: I’m traversing across many different types and predicates (see diagram below), though most the edges with resistance are purposefully one-directional.

Here’s my question, now:
I’m attempting to return all Resource (0…N) nodes that can be related to a single Skill node, S. Here’s what I have so far and it’s not working. There’s something about DQL execution or syntax that I’m missing (see code block):

{
  S as var(func: eq(XID, "Skill/NAICS/54"))

var(func: eq(dgraph.type,"Resource")) {
    uid
    path as shortest(from: uid(S), to: uid, numpaths: 1) { 
      Skill.Skills @facets(resistance)
      Skill.Resources @facets(resistance)
      Skill.Organizations @facets(resistance)
      Organization.Projects @facets(resistance)
      Project.ProjectRoles @facets(resistance)
      ProjectRole.Resource @facets(resistance)
    }
    
    path(func: uid(path)) {
     Name
     XID
    } 
  }
}

This query results in an error message: “line 8 column 30: Expecting argument name. Got: lex.Item [11] “(” at 8:30”, which appears to be in the shortest function line of code.

Thank you again for any advice you could offer.
