Error Deploying ASP.NET Core Web Application + ReactJS to Azure - reactjs

Question

Trying to deploy an ASP.NET Core Web Application + ReactJS to Azure and the Publish step in my pipeline always ends in error – “Error: The process 'C:\Program Files\dotnet\dotnet.exe' failed with exit code 1”
My pipeline is composed of:
Prepare job
Initialize job
Checkout
Restore
npm install (step added by me after some errors)
npm audit fix (step added by me after some errors)
npm run build (step added by me after some errors)
Build
Test
Publish <- Error!
Publish Artifact
Post-job: Checkout
Finalize Job
The error I get in the Pusblish step is:‌

Webpack compilation mode: production ===‌

Using “npm run build:prod” I thought the *.map files were not even necessary, but that is the only error I see on the Publish step.
Any help would be appreciated.
Thanks,

Remove npm publish step and try again. The npm publish step might be failing because the private property in package.json is set to true.
Try the Publish artifacts step and give the generated artifacts path ( drop or build folder) to the publish path step.
