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`.
