Failed to deploy artifacts: could not find artifact npm

Question

I am a new aspirant of Devops. Most of the blogs addressed related to "404 error Not found" are of maven projects. Can anyone explain how to resolve it for a react project? I am trying to deploy a react project onto nexus through ci pipeline[Jenkins].

For deployment, while configuring

//Following some blogs I tried these 2 ways:

1. Configuring .npmrc file
2. Altering package.json file

But neither have worked and still halted with the error. Now, I need:

1. What can be the cause of this error?
2. Are there any other ways to resolve the error? In perspective of npm format projects

Please help me

Thanks in advance
