Get a project measurement
Projects module
GET/project-measurements/{id}projectMeasurements.get
A figure measured on a project (Section 4.10) for one metric, day and source. A null value records that the figure was not measured (Unmeasured), never zero. Correcting the value, unit or day needs correction_reason and writes the change to the correction ledger. Who recorded it and when are created_by and created_at. Returns one project measurement with its `ETag`. A project measurement the caller may not see returns 404.
- Requires the capability projects.gate.read.
- OAuth scopes: projects.
- Error statuses: 400, 401, 404, 429. Errors are RFC 9457 problem details.
