Do 4xx errors not log to Apollo Router by default?

Hi there!

Just wondering, do 4xx errors not log to Apollo Router by default when the log level is set to info? For example an INVALID_GRAPHQL_REQUEST, would this be in the console/logs?

No but you can enable it by reading this documentation

Wouldn't this be for request headers though? I'm looking to log errors with a status code of 400, this seems to mean I need a request header, unless I am misunderstanding.

I was under the impression based on this issue, that these type of errors would log (not subgraph 200 errors but actual 4xx 5xx etc error responses)

By default no, for now the only option we have to enable logging for subgraph is by using the configuration I sent. And this configuration lets you enable logging for subgraph requests and responses but not only errors, it's everything. But we will improve this behavior regarding the feedback we received there.

Here is the configuration I'm using when I want to debug and see logs on every requests:

telemetry:
  experimental_logging:
    format: pretty
    display_filename: true
    display_line_number: true
    when_header:
      - name: "origin"
        match: ".*"
        headers: true
        body: true
