What causes "aspId or resId is empty" in OpenNHP/opennhp?

Populate both AuthServiceId and ResourceId on the ResourceData before the call

aspId or resId is empty

Error message

aspId or resId is empty

What it means

AddResource requires both ResourceData.AuthServiceId (which ASP owns it) and ResourceData.ResourceId (its key in the ASP's ResourceGroups map). If either string is empty the resource cannot be filed, so it is rejected up front.

Solutions

Populate both AuthServiceId and ResourceId on the ResourceData before the call
Fix the resource.toml entry so both fields are present and non-empty
Validate the ResourceData at construction time and skip/defect log invalid entries

Example fix

// before
srv.AddResource(&common.ResourceData{AuthServiceId: "asp-1"})
// after
srv.AddResource(&common.ResourceData{AuthServiceId: "asp-1", ResourceId: "web-portal"})

Defensive patterns

Strategy: validation

Validate before calling

func validResource(r *common.ResourceData) bool {
    return r != nil && r.AuthServiceId != "" && r.ResourceId != ""
}
if !validResource(res) { return errors.New("resource needs AuthServiceId and ResourceId") }
err := srv.AddResource(res)

Type guard

func resourceIsComplete(r *common.ResourceData) bool { return r != nil && len(r.AuthServiceId) > 0 && len(r.ResourceId) > 0 }

Try / catch

if err := srv.AddResource(res); err != nil {
    return fmt.Errorf("AddResource(asp=%q, res=%q): %w", res.AuthServiceId, res.ResourceId, err)
}

Prevention

Validate ResourceData immediately after config decode
Keep resource.toml field names in sync with the ResourceData struct
Fail the deploy if any resource entry lacks either id

When it happens

Trigger: Calling UdpServer.AddResource with a *common.ResourceData where AuthServiceId == "" or ResourceId == "".

Common situations: TOML resource entries missing the resourceId key; plugins building ResourceData from partial JSON where one field is absent; renaming a resource field in config and not updating the loader mapping.
