hoist-gql-errors

hoist-gql-errors extracts GraphQL errors from the downstream response and record them as OpenTelemetry exception events.

It aims at that Datadog Error Tracking collects errors from OpenTelemetry traces.

Datadog Error Tracking needs error types, error messages, and error stacktraces on service entry spans (top-level spans).

In typical web applications, top-level spans mean spans that started on http.Handler. In addition, otelhttp.Handler will record no exceptions from downstream spans.

These facts mean that Datadog Error Tracking tracks no errors from the spans started by default setup with otelhttp.Handler.

hoist-gql-errors hoists (downstream) GraphQL errors and records them as service entry spans' errors, and then Datadog Error Tracking correctly collects them.
