A session fails a specification when a scored evaluation of a metric linked to it did not pass. Counted over the sessions that `GET /analytics/sessions-overview` counts. ## OpenAPI ````yaml https://api.galtea.ai/openapi.json get /analytics/failing-specifications openapi: 3.0.0 info: version: 1.0.0 title: Product Management Service API description: API documentation for Product Management Service contact: name: Galtea AI servers: - url: https://api.galtea.ai security: - bearerAuth: [] tags: [] externalDocs: description: Galtea Platform Documentation url: https://docs.galtea.ai paths: /analytics/failing-specifications: get: tags: - analytics summary: List the specifications that sessions failed in a period description: >- The specifications of every product the caller may read that the filters keep that at least one session of the period failed, the highest share of failed sessions first, with the counts of the period of the same length just before it.
