Hey @dsriram3194 👋

That's a new one. GraphQL data isn't inherently cyclical, especially errors, so this is odd. Are you mutating data or errors in some way after the request in any way?

[fedebertolini]

The problem happens when the operation's context has a reference to an object with a cyclical structure. In my case, it was a reference to an opentelemetry tracer instance

[dsriram3194]

@jerelmiller, We found this to be an issue with how the GQL data is processed in our project and not with the library itself. Ill close this issue.
