Subgraph error inclusion


By default, the Apollo Router redacts the details of subgraph errors in its responses to clients. The router instead returns a default error with the following message:

Subgraph errors redacted

This redaction prevents potential leaks of sensitive information to the client. Using the include_subgraph_errors plugin, you can configure the router to propagate subgraph errors to clients instead. You can do this for all subgraphs, or on a per-subgraph basis.

Configuration

To configure subgraph error inclusion, add the include_subgraph_errors plugin to your YAML config file, like so:

router.yaml
include_subgraph_errors:
all: true # Propagate errors from all subraphs
subgraphs:
products: false # Do not propagate errors from the products subgraph

Any configuration under the subgraphs key takes precedence over configuration under the all key. In the example above, subgraph errors are included from all subgraphs except the products subgraph.
