Wildberries API TypeScript SDK / NetworkError

Class: NetworkError

Defined in: errors/network-error.ts:33

Network error thrown for connection failures, timeouts, and server errors.

This error is thrown for:

• Network connection failures (no internet, DNS failures)
• Request timeouts (exceeding configured timeout)
• 500-level server errors (500, 502, 503, 504)

The SDK's RetryHandler automatically retries network errors with exponential backoff (max 3 attempts), so transient failures are handled automatically.

Example

import { NetworkError } from 'daytona-wildberries-typescript-sdk';

try {
  await sdk.products.getProductList();
} catch (error) {
  if (error instanceof NetworkError) {
    if (error.isTimeout) {
      console.error('Request timed out:', error.getUserMessage());
    } else {
      console.error('Network error:', error.getUserMessage());
    }
    // The SDK already attempted 3 retries automatically
  }
}

Methods

getUserMessage()

getUserMessage(): string;

Defined in: errors/network-error.ts:73

Returns user-friendly error message with retry information and troubleshooting guidance

Returns

string

Error message with network-specific recovery steps

toJSON()

toJSON(): {
  name: string;
  message: string;
  isTimeout: boolean;
  statusCode?: number;
  response?: unknown;
  requestId?: string;
};

Defined in: errors/network-error.ts:120

Custom JSON serialization to preserve isTimeout property

Note: The cause property is not serialized as Error objects don't serialize well. Check the cause property directly if needed.

Returns

{
  name: string;
  message: string;
  isTimeout: boolean;
  statusCode?: number;
  response?: unknown;
  requestId?: string;
}
