Elastic Agent incorrectly logging items under ERROR

[jvalente-salemstate]

While troubleshooting an issue with Elastic Defend, and monitoring during installation of the integration, I am seeing that elastic_agent (all seemingly in runtime_service_command.go) is incorrectly logging other log levels as error.

See below, columns are timestamp, data_stream.dataset, log.origin.file.name, log.level, message

Examples from Defend's installation are included in the bottom as examples of where the level is working.
The message in the elastic_agent messages have various levels such as warning, info, and error but they're all being logged as error

• Agent Version: 8.12.0
• Elastic Agent Integration: v1.18.0
• Elastic Defend Integration: 8.12.0 (I've since installed 8.12.1-preview.0 but after the above logs were generated)
