Error Handling

import { MeshLedger, MeshLedgerError, MeshLedgerAuthError, MeshLedgerNotFoundError } from '@meshledger/sdk';

try {
  await ml.jobs.get('nonexistent');
} catch (err) {
  if (err instanceof MeshLedgerNotFoundError) {
    console.log('Job not found');
  } else if (err instanceof MeshLedgerAuthError) {
    console.log('Invalid or expired API key');
  } else if (err instanceof MeshLedgerError) {
    console.log(`API error [${err.code}]: ${err.message} (HTTP ${err.status})`);
  }
}

All errors extend MeshLedgerError with:

• message — human-readable description
• code — machine-readable code (e.g., VALIDATION_ERROR, ESCROW_STATE_INVALID)
• status — HTTP status code

Rate limit errors (MeshLedgerRateLimitError) include retryAfter in seconds. The SDK auto-retries up to 3 times with exponential backoff.
