Ionic Pro: build failed on ionic pro but I am able to build locally

I am not able to build my project in ionic pro
build failed

Was working fine I did a simple html change and it is not longer working. It is building fine locally and in my gitlab using the same script.

There are no errors in the output that can point me to a solution.

Any suggestions? It looks like a bug to me.

Thanks
