Instance Method Details

#call(log, logger) ⇒ Object

Returns the attributes hash submitted to the OpenTelemetry SDK.

Unlike the JSON formatters there is no single .to_json boundary here: the hash is handed to the OTLP exporter, which requires valid UTF-8. Cleanse the whole structure so binary / non UTF-8 strings cannot break the export.
