Why does my serverless-webpack deploy script "hang" with Webpack version 4.8 while running smoothly with version 3.12, and what are the steps to troubleshoot and resolve this issue?

The issue of your serverless-webpack deploy script "hanging" with Webpack 4.8 while running smoothly with version 3.12 could be due to several reasons. Here are some steps to troubleshoot and resolve this issue:

Common Causes Configuration Differences: Webpack 4 introduced several changes and new configurations that might not be compatible with your current setup.

Dependencies: Some dependencies might not be fully compatible with Webpack 4.8, causing the script to hang.

Build Process: Changes in the build process between Webpack 3.12 and 4.8 could be causing the script to hang.

Troubleshooting Steps Check Configuration: Review your Webpack configuration files for any settings that might be causing issues with Webpack 4.8. Ensure that all necessary plugins and loaders are correctly configured.

Update Dependencies: Make sure all your project dependencies are up-to-date and compatible with Webpack 4.8. You can use tools like npm-check-updates to check for outdated dependencies.

Review Logs: Enable detailed logging for your build process to identify where the script is hanging. You can use the --verbose flag with your deploy script to get more detailed output.

Test Locally: Try running the build process locally to see if the issue persists. This can help isolate whether the problem is with your local environment or the serverless deployment process.

Consult Documentation: Refer to the Webpack 4 documentation and any migration guides to ensure that your configuration is correct for Webpack 4.8.
