Errors

SDK errors are structured:

• NooschainSdkError: base SDK error.
• NooschainValidationError: local payload or input validation failed.
• NooschainHttpError: node API returned a non-2xx response.

HTTP errors include status, method, path, and a redacted response body when available.

Typical handling:

try {
  await client.transactions.submit(transaction);
} catch (error) {
  if (error instanceof NooschainHttpError) {
    console.error(error.status, error.method, error.path);
  }
  throw error;
}

Validation errors usually mean the SDK rejected local input before submitting. HTTP errors mean the node rejected or failed the request. A successful transaction submission still only means the node accepted the transaction for processing; contract execution or consensus validation can still fail later and should be checked through transaction receipts or contract call results.
