no table found for gvr: %s

Error message

no table found for gvr: %s

What it means

Workload.fetch asks the DAO's Table lister for objects and expects at least one item that is a *metav1.Table. The error fires when the list returns zero objects for the GVR, so there is no table to extract column definitions from.

Solutions

1. Confirm instances exist: kubectl get <resource> -n <ns>
2. Verify the GVR spelling/group via kubectl api-resources | grep <name>
3. If the namespace is legitimately empty, treat this as a no-data case in the caller instead of an error path
4. For aggregated APIs lacking table support, file/fix the extension server to implement table conversion

// Verify the GVR resolves and has instances before fetching the table.
gvr, err := factory.CanForResource(ctx, wantedGVR, client.ListAccess)
if err != nil { return err }
if oo, err := lister.List(ctx, ns); err == nil && len(oo) == 0 {
    return ErrNoData // treat empty as a valid state, not a table error
}

tbl, err := w.fetch(ctx, gvr, ns)
if err != nil {
    if strings.Contains(err.Error(), "no table found for gvr") {
        return nil, fmt.Errorf("%w — confirm with: kubectl api-resources | grep %s", err, gvr)
    }
    return nil, err
}

When it happens

Trigger: Calling Workload.fetch/ListDetail on a GVR that returns an empty list: namespace has no instances and the server omits the table object, the GVR string is wrong (typo, missing group), or the resource kind has no server-side table converter registered.

Common situations: Empty namespaces for custom resources; mistyped resource in a custom view or alias; aggregated API services that don't implement the Table accept header conversion.
