Worked on stabilizing browser automation within the FellouAI/eko repository, focusing on the eko-nodejs package. Addressed a critical issue in the page.evaluate method by correcting argument spreading, which previously led to runtime errors and unreliable automation tasks. The solution involved refining how arguments are passed and invoked within the browser context, ensuring functions execute as intended and reducing edge-case failures. This fix improved the reliability of automation flows and enhanced the developer experience by clarifying invocation semantics. The work was implemented using TypeScript and Node.js, leveraging browser automation expertise to deliver more stable and predictable automation behavior.
