failed to get version from server: %w

Error message

failed to get version from server: %w

What it means

An object type referenced by its qualified name is not defined. This is the object-type-specific variant: the resolver expected a defined object type (e.g. for a nested model output or command output) and could not find it.

Solutions

  1. Declare the object type in the metadata with the exact qualified name
  2. Correct the reference to the actual type name/namespace
  3. Verify all type files are included in the metadata source
Defensive patterns

Strategy: validation

Validate before calling

let objs: HashSet<_> = metadata.object_types.keys().collect();
for t in referenced_object_types(&metadata) {
    assert!(objs.contains(&t), "object type {t} not defined");
}

Prevention

When it happens

Trigger: Referencing an object type name as a field's type, command output, or nested structure when no object type with that qualified name is declared.

Common situations: Defining command outputs or nested object fields before defining the type itself; type renamed or moved to another namespace; missing type file in the metadata glob.
