While contributing to the AsyncAPI website, I encountered a critical issue that completely broke the production build. The entire website failed to load due to a small but impactful mistake in a JSON configuration file.
The problem was located in config/3.0.0.json, where an inline comment had been added inside the JSON object. Unlike JavaScript, JSON does not support comments. This caused a JSON parsing failure, which in turn triggered a Next.js build error and displayed an error overlay across all pages of the website.
To diagnose the issue, I closely examined the error message and traced it back to the exact line causing the failure. Once identified, the fix was straightforward: remove the unsupported comment and restore valid JSON syntax. After applying this change, the website compiled successfully and loaded without any errors.
This experience reinforced an important lesson for me: small syntax mistakes in configuration files can have site-wide consequences, especially in production systems. It also highlighted the importance of understanding format specifications and validating configuration changes carefully.
Through this contribution, I gained hands-on experience debugging a real-world issue, working with build systems, and contributing to the stability of an open-source project. It was a reminder that meaningful open-source contributions aren’t always about adding new features—sometimes they’re about preventing failures and improving reliability.
