As a Solana developer, you are not alone in encountering this frustrating error. The “candy machine” issue can cause deployment issues when you try to deploy your NFTs and metadata. In this article, we will walk you through the steps to resolve this issue and help you get back on track.

Issue: Candy Machine Error

When you encounter a Solana “candy machine” (also known as “baking”) error during deployment, you will see an error message similar to the one below:

I am encountering this issue when trying to deploy my NFTs and metadata. Can anyone help?
[2/2] Writing configuration lines
Sending configuration lines in 7 transactions: (Ctrl+C to cancel)
[00:00:01] Deploying...

This error occurs because the Solana SDK is trying to create a configuration for your deployment, but it encountered a problem that prevented it from doing so. The term “candy machine” refers to the process of creating a new block with a specific configuration.

Why is this happening?

The “candy machine” issue can occur for a variety of reasons, including:

• Inconsistent or incorrect configuration files

• Errors in the Solana SDK config module

• Issues with the transaction signing process

Troubleshooting Steps: Resolving the Issue

To resolve this error and successfully deploy NFTs and metadata, follow these steps:

• Check Configuration Files: Verify that your configuration files are consistent and accurate.

• Rerun Solana SDK: Try running the Solana SDK again with updated configuration files to see if this resolves the issue.

• Inspect Transaction Signing Process: Verify the transaction signing process to make sure everything is correct.

• Update SDK version

  : Make sure you are using the latest version of the Solana SDK.

Configuration lines: writing in 7 transactions

To write configuration lines in 7 transactions, follow these steps:

• Use solana-program, solana-sdk, or other libraries that support multi-transaction writing.

• Create a config.json file with the desired configuration settings.

• Write the configuration lines using the library API.

// config.json
{
"keychain": {
"path": "/path/to/keychain",
"password": "your_password."
},
"network": {
"rpcUrl": "
"gazPret": 20,

}
}
