} from '@dotcms/types';

// Type-safe error handling
if (error instanceof DotHttpError) {
  // Access standardized HTTP error properties
  console.error(`HTTP ${error.status}: ${error.statusText}`);
  console.error('Response data:', error.data);
}

if (error instanceof DotErrorPage) {
  // Page-specific error with GraphQL context
  console.error('GraphQL query:', error.graphql?.query);
}

if (error instanceof DotErrorContent) {
  // Content-specific error context
  console.error(`${error.operation} failed for ${error.contentType}`);
