Hi,

I understand that you are encountering a login error with Metronic's Laravel Starterkit. The error you mentioned, typically occurs when the required JavaScript file is missing or not properly generated during the build process.

Please make sure you have run the command "npm run dev" in your Laravel project directory. This command is necessary to compile and generate the required assets, including the JavaScript file mentioned in the error.

After running the "npm run dev" command, please try accessing the login page again, and the error should be resolved.

If you continue to face issues, I recommend checking the documentation provided for the Laravel Starterkit. It contains detailed instructions on setting up and running the project correctly. You can find the documentation at the following link:
