Worked on the elastic/terraform-provider-elasticstack repository, focusing on improving code quality and reliability rather than delivering new features. Addressed a critical bug by correcting a recurring typo in error messages within the Kibana client and Elasticsearch security API key modules, changing 'Unabled' to 'Unable' to enhance clarity and professionalism in user-facing error reporting. This non-breaking update, implemented in Go, improved error handling and reduced potential confusion for developers and end users. The work demonstrated attention to detail and a commitment to cross-module consistency, laying the foundation for future automated validation of error messages without altering existing API behavior.
