Module: PlatformSdk::Observability::Langfuse::Coercions

Defined in:
lib/platform_sdk/observability/langfuse/coercions.rb

Overview

Shared coercion helpers used by Configuration, Recorder, and the Traceable PerformWrapper. Extracted to a single home so the OpenTelemetry attribute-validator workaround (String.new to produce a plain String rather than a subclass) lives in one place.

Class Method Details

.coerce_string(value) ⇒ Object

Returns nil for nil; otherwise a plain String (not a subclass). OTel's attribute validator uses instance_of?(String) — subclasses like ActiveSupport::SafeBuffer fail validation and crash Resource.create.
