Allow user to hook into Breadcrumb in SentryInstrumentation

[ooraini]

Problem Statement

I want to add more data into the breadcrumbs generated by SentryInstrumentation,. As a use case, I want to add any parameter named id when resolving any field: user(id: "..."). I could use context data, but with nesting it will not work. Example breadcrumb from sentry.io:

{
field: createXyz,
object_type: Mutation,
path: /createXyz,
type: createXyzPayload

...hook for more data

}

There are two places where breadcrumbs are used in SentryInstrumentation: beginExecuteOperation and instrumentDataFetcher. I'm not sure about beginExecuteOperation, but instrumentDataFetcher is mostly where I want to enrich the breadcrumb.

Solution Brainstorm

Nested class in SentryInstrumentation

interface DataFetcherBreadcrumbEnricher {
        void enrich(DataFetchingEnvironment environment, Breadcrumb breadcrumb);
}

Hey @ooraini thanks for opening this issue.

We're thinking this through and our current solution would be to add a Hint containing more details which you could then use in beforeBreadcrumb to enrich the breadcrumb. Would this work for you?

If yes, what GraphQL data would you need? Just DataFetchingEnvironment, or anything else?

For this to work you'd have to register a beforeBreadcrumb callback, similar to what is shown in docs but for Spring Boot you can provide a bean of type SentryOptions.BeforeBreadcrumbCallback which should automatically be picked up and used by auto init of the Spring Boot SDK.

As long as I can access the DataFetchingEnvironment , it should work out.

The DataFetchingEnvironment contains everything that I would need, I thought of including the result of the data fetcher as well, but that seems an overkill, and BeforeSendCallback already has it.
