I have a mono repo. It includes a private package. The problem I am having is with my github actions pipeline. I can download the private library to run tests on one of my projects in the runner. However, when I attempt to execute a CDK later in the pipeline following similar steps, it doesn’t find the module.

What is confusing me, is the error message isn’t what you would normally see if the NODE_AUTH_TOKEN wasn’t applied correctly. The runner appears to download the module during npm i, but then can’t seem to find it at run time.

I am sure I am missing something obvious.

Here is the CDK action I am expecting to be able to deploy CDK.
