React Docker, problems with build pipeline

[zjpiazza]

I have a relatively simple React application with a Dockerfile that I’m trying to deploy to Azure App Service. When I build the docker image locally, everything works as expected. However when I try and run the image from the build pipeline, im seeing “.map is not a function” on two of my views. It’s a simple map to render some JSX. Using dev server and locally built it works completely fine. I’m totally at a loss I have no idea what the issue could be. There’s clearly some dependency I’m missing or something different about the environment on the build server causing this issue.

Dockerized React application works locally but fails when built by ci pipeline
