Deploying application to Azure DevOps

I am attempting to deploy my working version to an Azure DevOps hosting site and I am getting the following error:

14292 error code E404
14293 error 404 Not Found - GET https://registry.npmjs.org/@infragistics%2figniteui-angular - Not found
14294 error 404

##[error]Error: Npm failed with return code: 1

Is there something I need to add to the YML/TF scripts for the build pipeline in order to access the paid subscription so my build goes through properly? I remember having to set a build variable in NPM for my local but I can’t find the page and I don’t remember it saying anything about applying the same changes to an automated build location.

Looking at the error that you are getting, it seems that you are missing the configuration for our private repository. We have an article which you can refer to for more details how to setup your Azure DevOps build – https://www.infragistics.com/products/ignite-ui-angular/angular/components/general/ignite-ui-licensing#azure-pipelines-configuration.

Please let me know whether I can assists you with anything else on the matter.

I have integrated the steps and variables as specified and am still getting errors:

I am directly injecting the variables (blocking IG token below) in my ui-pipelines.yml:

# Starter pipeline
# Start with a minimal pipeline that you can customize to build and deploy your code.
# Add steps that build, run tests, deploy, and more:

Can you please tell me why it's still failing?

The error indicates that the npm is still not configured and when installing our package, npm still searches it under the npmjs.org repo(GET https://registry.npmjs.org/@infragistics….). You can check the .npmrc file after the configuration steps by outputting it with npm list command. You can try to update the .npmrc file by redirecting the output with "TEXT" >> ~/.npmrc.
Another thing is to check whether you have a local .npmrc file per your project, which "shadows" the global one which has been updated with above steps. 

I'm glad that you were able to configure your Azure pipeline to install our @infragistics/igniteui-angular package.
