Suboptimal UX on Too Many Requests to forking origin

[FabijanC]

Coming from this Discord message:

Hello, I ran into a problem, when invoking a write transaction on devnet I get this error: Failed to read from state: Error in communication with origin: Received response with status: 429 Too Many Requests.. Has anyone seen this before?

this is how we started it:

export STARKNET_RPC='<URL for free rpc nethermind mainnet-juno>'
sudo docker run --network host shardlabs/starknet-devnet-rs --fork-network $STARKNET_RPC --seed 69420

So, it seems that there were too many requests to the forking origin made by the Devnet instance. Here are some thoughts:

1. It could be a temporary network issue, so try re-running your program.
2. If forking (i.e. interaction with the origin behind $STARKNET_RPC) is not crucial for your use case, feel free to omit the --fork-network parameter.
3. Change the forking origin URL
4. Consider adding short sleeps to your program which communicates with Devnet
5. The Devnet team can consider introducing a better handling for the 429 Too Many Requests scenario, such as automatically re-sending the request after waiting for a short period of time, or simply improving the returned error message.
