Node js rejected with "we found it isn't at the quality standard required to move forward" reason

Hi everyone, I’m new on this platform. I do not know how it makes sense, but my story:

  • Firstly I submitted the project and after 6 days soft reject came. After correcting my mistake, I received a hard rejection saying that the plant did not meet the quality standards.

To fix my mistakes, I am currently doing the necessary planning by looking at link.

Meanwhile, the project is a Bulk Mail project.

I am a back-end developer. I do not know if I have front-end errors but everything works fine … if there is a mistake and you can say it, I am very happy
