Hi There,
I am setting up the custom middleware
var methodFilterMiddleware = new TykJS.TykMiddleware.NewMiddleware({});
methodFilterMiddleware.NewProcessRequest(function(request, session, spec) {
var requestBody = JSON.parse(request.Body);
var allowedMethods = ["subgraph_create", "subgraph_deploy"];
if (allowedMethods.indexOf(requestBody.method) === -1) {
// Method not allowed
return TykJsResponse({
Body: "Method not allowed",
Headers: {
"content-type": "application/json"
},
Code: 403
});
}
return TykJsResponse(requestBody, request.Headers, 200);
});
but getting below error in the logs
time="Apr 09 20:27:05" level=error msg="Failed to run JS middleware" api_id=public-node-indexer api_name=public-node-indexer error="TypeError: Cannot access member 'Headers' of undefined" mw=DynamicMiddleware org_id=1 origin=172.16.19.4 path=/indexer

What I am trying to achieve here is if the method is subgraph_create or subgraph_deploy it should return 200 OK, else 403, below the the query which should work, but even when I am trying with subgraph_remove it still works and give me the above error in the logs.
curl --location 'hostname/indexer' \
--header 'Authorization: API-KEY' \
--header 'Content-Type: application/json' \
--data '{"method":"subgraph_create","jsonrpc":"2.0","params":{"name":"test_himanshu"},"id":"250"}'
