Hey, i tried to do a basic query to my graphql endpoint using fragments
When i do it directly to my graphql endpoint it works perfectly but when it goes through tyk it doesn’t
Normal query works using tyk so the problem is specifically with fragments i guess.
This is the example when i only get typename(doesnt belong to the fragment fields)
The other is a working example of what the response should look like (directly to the endpoint)
Thanks in advance !
Hey @itzhakyos
could you let me know which Tyk version you’re on? I just tried replicating this problem on v5.2 and was not able to, fragments worked just fine. I checked our Dashboard Playground, the public Playground (which I think you were using to do your screenshots) and via Postman as well.
Would be great to get a bit more detail: Tyk version - as mentioned already, logs if you’ve got anything available.
Also attaching the screenshot from my test in public Playground.
Hey,
I am using version 5.0.1
Thank you in advance !
I tried to replicate your problem on a few different versions, including 5.0.1, and I am still getting fragments to work as they should. No issues whatsoever.
Is there anything “special” about your upstream? From the looks of it, it seems like a pretty standard GQL API, but obviously I just see the Playground screenshots, not the service itself.
Also - what are you getting the the gateway logs? Something similar to the below or something else?

when i try using this query with fragment in the playground outside of the gateway dashboard what i shoed above were the results.
But i notice that when i use the internal playground with the exact query using fragment there is a response:
{
“message”: “fragment spread: my-fragment-name forms fragment cycle”,
“path”:[
“query”,
" my-fragment-name "
]
}
Hello @itzhakyos,
I’m currently looking into your issue but unfortunately, your provided information is not enough to reproduce the issue.
Can you please provide a (minimal) schema and the operation (if possible as copyable text)?
Thank you!
yes
i have a type:
gql interface StaticEntity { id: String kind: String }
some other types:
gql union StaticEntityTypes = Circle | Corridor
gql type Circle implements StaticEntity { id: String kind: String }
gql type Corridor implements StaticEntity { id: String kind: String }
gql type Query { myArea(ts: String): [StaticEntityTypes] }
and then i do a query from the client:
fragment GenericStaticEntity on StaticEntity{
id
kind
}
query MyArea($ts: String){
MyArea(ts: $ts) {
…GenericStaticEntity
_typename
}
}
everything works perfectly when i go directly to my graphql endpoint
but when i go through tyk the results are as i showed above
Hello @itzhakyos,
I’ve tried following setup now:
Schema
union StaticEntityTypes = Circle | Corridor
interface StaticEntity {
id: String
kind: String
}
type Query {
myArea(ts: String): [StaticEntityTypes]
}
type Circle implements StaticEntity {
id: String
kind: String
}
type Corridor implements StaticEntity {
id: String
kind: String
}
Operation
fragment GenericStaticEntity on StaticEntity{
id
kind
}
query MyArea($area: String) {
myArea(ts: $area) {
...GenericStaticEntity
__typename
}
}
Variables
{"area": "HE"}
Can you check if my setup resembles yours? Currently, I’m not experiencing the error you are, so I want to make sure, that everything is the same.
If this issue is blocking you, try to avoid fragments for this use case for now (as Tyk will remove the fragment internally anyway)
Thank you!
I tried your setup and it does not work…
Unfortunately changing our project to work without fragments is not realistic at the moment,
because there we use it a lot inside a big project.
