Error: html-webpack-plugin could not minify the generated output

I’m experiencing difficulties getting my site to deploy. My build settings and build log are below. The site name is https://stupefied-yalow-b06154.netlify.app/. Any advice that can be offered to help me get my site deployed would be greatly appreciated. Thank you in advance, :pray:.

  • I’m curious if the trouble deploying has to do with the following:
    5:30:06 PM: Failed to compile.
    5:30:06 PM:
    5:30:06 PM: Error: html-webpack-plugin could not minify the generated output.
    5:30:06 PM: In production mode the html minifcation is enabled by default.
    5:30:06 PM: If you are not generating a valid html output please disable it manually.
    5:30:06 PM: You can do so by adding the following setting to your HtmlWebpackPlugin config :
    5:30:06 PM: |
    5:30:06 PM: | minify: false 
  • If so, how do I go about fixing this?

Adding that, like I have done, fixes the issue.
