Generates a unique identifier for each request on the Akamai edge network, for use in logging and debugging. GRN identifiers follow the same format as Akamai's error reference strings, for example: 0.05313217.1567801841.1457a3. You can use the Edge Diagnostics API's Translate error string operation to get low-level details about any request.
