Cannot run direct three-hop ARAGORN queries for Workflow B about aragorn

Apparently, I cannot assign anyone to this issue, so I'll suggest @cbizon and @patrickwang.

A few things:

With real_world_whatever, what you are getting is 0 responses. That's because (I think?) KPs are not exposing this predicate in their meta_knowledge_graph endpoints. At least when I just checked ICEES, I didn't see it. Unless it's in there, we have no way to run the query.

With correlated_with, strider is putting together about 13000 answers, so that seems to be working fine, but aragorn is causing a 500. So that part is not something you're doing, it's our bug to fix.

I've verified that this is a bug in AC somewhere. I think it's a botched biolink issue. But anyway, you can send a workflow to aragorn to bypass AC for the moment. So you can make your query look like:

{
"message": messagestuff,
"workflow": ["lookup","connect_knodes","score"]
}

I've verified that this works when sent to aragorn.

WRT biolink:has_real_evidence_of_association_with, I don't think the meta-KG is the issue. Specifically, the ICEES DILI instance returns results to this query when run directly against ARAX: https://arax.ncats.io/?r=18599. Hao and Patrick fixed the meta-KG issue, which was actually with the ICEES asthma instance, not the ICEES DILI instance, but when Hao later tested the query by running it directly against ARAGORN, it returned no results. So, I think something else is going on.

The workflow trick worked, however, so that much is good.

Tried just running the 1-hop directly on ICEES DILI, and got 62 results. Same query through strider, 0 results. It looks like the KP is registered, and has the has_real_evidence... predicate. Furthermore, strider reports that it is calling ICEES DILI, but not getting any results back. Also strange, it appears to be calling many KPs that I don't think should have this predicate, like covidkop.

Assigning @patrickkwang to pick up the strider thread.

This was the query:

{
    "message": {
        "query_graph": {
            "nodes": {
                "n0": {
                    "ids": [
                        "MESH:D056487"
                    ],
                    "categories": [
                        "biolink:DiseaseOrPhenotypicFeature"
                    ]
                },
                "n1": {
                    "categories": [
                        "biolink:DiseaseOrPhenotypicFeature"
                    ]
                }
            },
            "edges": {
                "e01": {
                    "subject": "n0",
                    "object": "n1",
                    "predicates": [
                        "biolink:has_real_world_evidence_of_association_with"
                    ]
                }
            }
        }
    }
