Add more granular try catches in /plugin-coinbase

[monilpat]

Feature Request

Is your feature request related to a problem? Please describe.
The current error handling in the /plugin-coinbase directory lacks granularity, making it difficult to identify specific failures in the transaction process.

Describe the solution you'd like
Implement more granular try-catch blocks throughout the /plugin-coinbase code to improve error handling and logging. This would allow for more detailed error messages and better debugging capabilities.

Code Example

try {
    // Code that may throw an error
} catch (error) {
    console.error('Specific error message:', error);
    // Handle specific error
}

Describe alternatives you've considered
Leaving the current error handling as is, but this may lead to difficulty in troubleshooting issues.

Additional context
Improved error handling will enhance the reliability of the plugin and provide clearer insights during failures, ultimately leading to a better user experience.
