Docker engineer required to bug fix a docker build error

I have a dockerfile that builds a Laravel App and has worked until recently when the build started failing.

I need an engineer to bug fix the build fail.

The Dockerfile: -

Builds PHP Alpine
Installs MS ODBC Driver for SQL Server
Verify's signature
Installs apk packages
Installs extensions
Installs my Laravel app

The bug is somewhere in those steps in the Dockerfile.

I can grant access to the repo through a Personal Access Token.
