Question: Possible to only attach breadcrumbs when an error occurs?

[watadarkstar]

Description

I'm wondering if there is a way to only attach the network request as a breadcrumb if there are graphQLErrors or a networkError occurs, otherwise don't attach a breadcrumb.

Context: The main reason I want this is because I think adding a ton of sentry breadcrumbs is going to be a performance hit. I might be wrong?

Code

For example, I do this inside my onErrorLink but I would love to use this library instead to attach breadcrumbs only when a network/graphql error occurs.

const onErrorLink = onError(({ graphQLErrors, networkError, operation, forward }) => {
  if (graphQLErrors) {
    graphQLErrors.forEach(({ message, locations, path }) => {
          sentryBreadcrumb(
        `[GraphQL error]: Operation: ${operation.operationName}, Message: ${message}, Location: ${locations}, Path: ${path}`
      )
    }
if (networkError) {
    sentryBreadcrumb(`[Network error]: Operation: ${operation?.operationName}`, {
      networkError,
      operation: JSON.stringify(operation),
    })
  }
}

Breadcrumbs are only sent to Sentry along with an error that occurs later.
