Local to production deployment environment discrepancies

One of the most persistent issues is 'it worked on my machine,' where an application functions correctly in a development or testing environment but fails in production. This happens when environments are not consistent, and teams waste significant time chasing bugs caused by configuration discrepancies.

Local development is a massive pain with random bugs. The response time of the database also varies all over the place.

Inconsistent test environments, so "it worked in sandbox" didn't mean much

'It works on my machine' might be the most frustrating phrase in software development. Environment inconsistencies waste countless hours on debugging issues that only appear in specific environments.

Deployment environment discrepancies further complicate implementations, as functions that work locally may fail in production environments, exemplified by Axios errors occurring exclusively in deployed web applications
