Worked on the electric-sql/electric repository to enhance the accuracy of API documentation by correcting a typo in the OpenAPI specification, changing 'pattenProperties' to 'patternProperties'. This update focused exclusively on documentation, ensuring the API spec adheres to proper syntax and reducing the risk of client misinterpretation. The work involved editing YAML files and applying strong attention to detail in documentation practices, with no changes made to the underlying codebase or API functionality. By aligning the documentation with the correct property name, the update improved API discoverability and provided a clearer developer experience for users referencing the OpenAPI documentation.
