npm ERR! code ELIFECYCLE npm ERR! errno 1 npm ERR! build webpack --mode production npm ERR! Exit status 1

This error message is indicating that there was an issue with the build process of an npm package. The "ELIFECYCLE" code typically indicates that a script that was run during the build process failed to execute properly, and the "errno 1" message indicates a generic error.

In this specific case, the error occurred while running the "webpack --mode production" command, which suggests that there may be an issue with the configuration or setup of the webpack build process.

To troubleshoot this error, you may need to review the webpack configuration file and ensure that all necessary dependencies are installed and correctly configured. Additionally, you could try running the command with the "verbose" flag to get more detailed output and identify the specific error that occurred.
