Hello,
I'm breaking my head with this one for a few hours.
I have a proxy that uses the graphql policy to proxy to a graphql target host.
The graphql policy seems to be execute just fine and I get a successful response from the target server.
Now, i trying to access the flow variables as described in - https://cloud.google.com/apigee/docs/api-platform/reference/variables-reference#graphql so that i can calculate query complexity and quota variables before the request hits the target.
I included a javascript policy just after the graphql policy to read the flow variables(primarily looping over the graphql.operation.selectionSet), but I keep getting an error trying to get to these properties.
Javascript policy code
var graphql = context.getVariable("graphql");
print("graphql: " + graphql);
print("graphql.operation: " + graphql.operation);
print(Object.getOwnPropertyNames(graphql));
The print on line 2 runs fine and returns
graphql: com.apigee.steps.graphql.object.GraphQLPayload@c54eb01
assuming it's a toString implementation of the object
The print on line 3 returns
graphql.operation: undefined
As I couldn't get to an operation object i tried to introspect the graphql object but line 4 causes the following error
Execution of JavaScript-1 failed with error: Javascript runtime error: "TypeError: Expected argument of type object, but instead had type object. (JavaScript-1.js:3)"
which is extremely strange!
What am i doing wrong ?
