Error handling

Each database operation returns an error object in the callback function:

On success, null will be returned
On error, the error object is populated.

Error Object

Error objects are of class AerospikeError and include the following properties:

code — The operation status.
message — The message corresponding to an error code. Can be an empty string if the operation completed successfully.
func — The function in which the error occurred. Can be NULL if not captured properly in the operation.
file — The file in which the error occurred. Can be NULL if not captured properly in the operation.
line — The line number in the file in which the error occurred. Can be 0 if not captured properly in the operation.

This example handles an error from a put() operation:

try {
  await client.put(key, bins);
} catch (error) {
  console.error("error: %s [%d]\n%s", error.message, error.code, error.stack);
  process.exit(-1);
}
