can't link from organism specific pathways

[rmflight]

kegg_pull version 3.1.0

When doing an organism specific linking of pathway to compound, it returns an empty value.

# doesn't work
kegg_pull map link entry-ids path:hsa00010 compound
{}

# works
kegg_pull map link entry-ids path:map00010 compound

{
  "path:map00010": [
    "cpd:C00022",
    "cpd:C00024",
    "cpd:C00031",
    "cpd:C00033",
    "cpd:C00036",
    "cpd:C00068",
    "cpd:C00074",
    "cpd:C00084",
    "cpd:C00085",
    "cpd:C00103",
    "cpd:C00111",
    "cpd:C00118",
    "cpd:C00186",
    "cpd:C00197",
    "cpd:C00221",
    "cpd:C00236",
    "cpd:C00267",
    "cpd:C00354",
    "cpd:C00469",
    "cpd:C00631",
    "cpd:C00668",
    "cpd:C01159",
    "cpd:C01172",
    "cpd:C01451",
    "cpd:C05125",
    "cpd:C06186",
    "cpd:C06187",
    "cpd:C06188",
    "cpd:C15972",
    "cpd:C15973",
    "cpd:C16255"
  ]
}

I feel like the first case should work, especially as all of the compound entries shown on KEGG itself are shown with the organism specific pathway, not the generic one.

I've sent this feedback to KEGG:
"The link endpoint in the REST API is not able to get organism specific links. For example, this URL is valid:
https://rest.kegg.jp/link/pathway/compound

But replacing pathway with hsa results in an invalid URL:
https://rest.kegg.jp/link/hsa/compound

Here is another example:
https://rest.kegg.jp/link/compound/path:map00010

That URL works, but when replacing with the ID of a human specific pathway, it does not:

https://rest.kegg.jp/link/compound/path:hsa00010

It would be helpful to be able to link database entry IDs to the IDs of organism specific pathways."
