Hi,
Apollo Federation adds traces to the payload returned by subgraphs. The payload usually looks like:
{“data”: {…}, “extensions”: {“ftv1”: “…”}}
In my case, the value of “ftv1” is very very big (several MB), which makes the gateway throw a 502 error, since the payload exceeds the max value allowed by AWS Lambda (~6MB I think).
Since this tracing feature seems quite standard, I’m wondering if there is a problem regarding my implementation, or if it’s supposed to be that big?
NB: I know I can disable it with ApolloServerPluginUsageReportingDisabled plugin, but I need to monitor my queries performances in Apollo studio. There is no problem if I use a standard Apollo Server without Federation.
