[Relay White Noise Error] Correct Mapping of Rate-Limiting Errors (429 Handling)

[quiet-node]

Problem

Currently, the Relay incorrectly maps 429 Too Many Requests responses from the Mirror Node to 409 Conflict before returning them to clients. This misalignment causes:

• Clients being unaware of rate limits, potentially leading to excessive retries.
• A lack of clarity regarding whether failures are due to conflicts or rate limits.
• Potential inconsistencies in error handling across different RPC endpoints.

Solution

• Ensuring that 429 Too Many Requests from the Mirror Node is correctly returned as 429 to clients.
• Maintaining consistency in how rate-limiting responses are handled across different endpoints.
• Improving client awareness of rate limits, reducing unnecessary load on the Relay and Mirror Node.
