Description
What version of OpenTelemetry are you using?
@opentelemetry/api v 1.4.1
What version of Node are you using?
18.16.0
What did you do?
Create a GraphQL API (I'm using Apollo but I don't believe it matters) with a query, mutation, or a field on an individual type whose response type is a union, eg:
type Foo {
field: String
}
type Bar {
anotherField: String
}
union MyUnion = Foo | Bar
type Query {
fooOrBar: MyUnion!
}Then execute a GraphQL query, eg:
{
fooOrBar {
...on Foo {
myField
}
...on Bar {
anotherField
}
}
}What did you expect to see?
Resolve spans for each resolver that ran (eg. if a Foo is returned, a span for fooOrBar and myField)
What did you see instead?
A single resolve span for the query field only (fooOrBar). This is the case no matter how deeply the query nests.
Additional context
I'm using the node SDK to instrument automatically. I also made sure to set ignoreTrivialResponseSpans to false and depth to -1 (I know they are defaulted, but I wanted to be sure it wasn't related) like so:
const sdk = new opentelemetry.NodeSDK({
// other settings...
instrumentations: [getNodeAutoInstrumentations({
'@opentelemetry/instrumentation-graphql': {
ignoreTrivialResolveSpans: false,
depth: -1,
},
})],
});
