tyk-gateway OSS v4.1.0-rc10.
I’m using Tyk in GraphQL supergraph-subgraphs setting. I’m trying to query an introspection info:
query SampleIntrospectionQuery {
__type(name: "Character") {
name
}
}
An expected response is:
{
"data": {
"__type": {
"name": "Character"
}
}
}
But the whole GraphQL schema is returned instead:
{
"data": {
"__schema": {
"queryType": {
"name": "Query"
},
# skipped
I found out that I can make Tyk to return the requested introspection info only. I just need to add some other field to my query. An example:
query SampleIntrospectionQuery {
__type(name: "Character") {
name
}
characters { # I don't actually need this field
results {
gender
name
}
}
}
With the query above Tyk returns an expected response (not mentioning the useless characters field).
Here is my setting:
