Error Handling in Solana: YellowgRPC Geyser Plugin
As a developer working on the popular Solana blockchain, you may have encountered issues while building applications that use the Yellowstone-grpc geyser plugin. In this article, we will delve into Solana’s error handling mechanism and explore how to resolve the “Error: Received message larger than maximum”.
What is the YellowgRPC geyser plugin?
The Yellowstone-grpc geyser plugin allows you to build a Solana RPC client that leverages the power of the grpc library to discover gRPC services. This plugin provides an easy way to manage and interact with your application’s services while keeping your codebase clean and easy to maintain.
Error: Received message larger than maximum
When attempting to retrieve data from a locally hosted RPC server using the Yellowstone-grpc geyser plugin, an error may occur when attempting to handle large messages. This issue occurs because the “max” parameter set in the gRPC client options is too small to handle large payloads.
Solana throws the “Error: Received message larger than maximum” error when a message is encountered that exceeds the maximum allowed size. This can occur for a variety of reasons, including:
- Large amount of data being sent over the network
- Inconsistent message length across services
- Misconfigured RPC server settings
Workaround
To resolve this issue, you need to adjust the gRPC client options to handle larger messages. Here are some steps to take.
- Update the “max” parameter: Increase the “max” parameter in the gRPC client options to accommodate the higher load. You can do this by adding a new option to the “ClientOptions” object, for example:
const client = new client({
// ... other settings ...
options: {
maxMessageSize: 67108864, // increase the default value from 1970303084
},
});
- Specify the message length: You can also specify a fixed-length message to ensure that your RPC server does not receive unnecessarily large messages.
Here is an updated example:
const client = new client({
// ... other settings ...
options: {
maxMessageSize: 67108864,
maxLength: 2000, // set the maximum message length
},
});
- Test and improve: Once you have made these adjustments, thoroughly test your application to ensure that it works as expected. If necessary, improve your gRPC client code to accommodate higher loads.
Conclusion
By understanding how the Yellowstone-grpc geyser plugin works and adjusting its options accordingly when retrieving data from a locally hosted RPC server, you should be able to resolve the “Error: Received message larger than maximum” issue. Don’t forget to test and improve your application after making these adjustments to ensure a smooth experience for your users.
Code example
Here is an example of how to update the gRPC client code using the updated options.
const Client = require('@triton-one/yellowstone-grpc');
async function getHelloWorld() {
const client = new Client({
// ... other settings ...
options: {
maxMessageSize: 67108864,
maxLength: 2000, // set the maximum message length
},
requestHandler: async (request, response) => {
console.log('Message received:', request.message);
response.send({data: 'Hello world!' });
},
});
try {
const {data} = await client.getHelloworld();
console.log(data);
} catch (error) {
console.error(error);
}
}
getHelloWorld();
This updated code increases the “maxMessageSize” option and sets a fixed message length (“maxLength”) to ensure that your RPC server does not receive unnecessarily large messages.
