Solutions

  1. Remove the model arguments GraphQL input configuration block

Example fix

# before
graphql:
  model_arguments:
    input_type_name: UserArgs
# after
graphql: {}
Defensive patterns

Strategy: validation

Validate before calling

if model.arguments.is_empty() {
    assert!(model.graphql.model_arguments.is_none(), "unnecessary arguments config");
}

Prevention

When it happens

Trigger: Configuring model arguments input (e.g. argument input type names) on a model whose command signature declares no arguments.

Common situations: Removing arguments from a command but leaving the GraphQL arguments config behind; copy-pasted model metadata.
