Deploying Solana Contracts to the Local Network: Troubleshooting Guide
Solana is a popular, fast, and scalable blockchain platform that allows developers to build decentralized applications (dApps) and participate in the Solana network. However, one of the most common problems when deploying Solana contracts to a local network is that errors occur during the deployment process. In this article, we will explore the causes of this problem and provide a step-by-step guide to resolve it.
Error Message
When you try to deploy (anchor) the Solana contract on your local network, you receive the following error message:
Cluster deployment:
Updating permission: /Users/bla/.config/solana/id.json
Deploying the program...
This error indicates that your Solana client is trying to connect to a local network node at ” This is the default local network port used by Solana clients, but you are trying to update the anchor contract using a different endpoint.
Reasons for the issue
There are several reasons why your Solana customer may be having issues deploying local network contracts:
- Invalid upgrade authority: The upgrade authority field in the .id.json file should point to a local network node, not a regular Solana node.
- Wrong cluster: Make sure the cluster you are trying to deploy to is actually the local network and not another network (e.g. mainnet).
- Local network node not started: Make sure the local network node is started and running before attempting to deploy contracts.
Solutions
To resolve this issue, follow these steps:
- Check your .id.json file: Make sure the Upgrade Authority field points to a node on your local network, for example:
{
"Name": "Localnet-01",
"Path": "/Users/bla/.config/solana/id.json"
}
- Check Localnet Node: Make sure the Localnet node is up by checking its logs or using a command line tool like solana-cli:
solana-cli --port=8899 --node=/path/to/localhost-node
- Use the correct cluster: Make sure the cluster you want to deploy to is is on-premises and not on another network:
{
"name": "localnetwork",
"path": "/users/bla/.config/solana/id.json"
}
- Check the status of the local network node: Check the status of the local network node using a command line tool like “solana-cli” or Localnet Explorer:
solana-cli --port=8899 --node=/path/to/localhost-node
Conclusion
Deploying Solana contracts on a local network can be challenging, but with these troubleshooting steps and solutions, you should be able to resolve the issue and successfully deploy the anchor contract. Be sure to check your .id.json file, local network node configuration, cluster settings, and Localnet Explorer output to make sure everything is correct before you begin deployment.
By following this guide, you can avoid common mistakes when deploying Solana contracts to your local network and start building scalable and secure decentralized applications (dApps) on the Solana blockchain.
