GraphQL subscriptions are not working

[venkat-bhogavilli]

HI,
I am using docker mesh from https://github.com/onelittlenightmusic/graphql-mesh-docker.
I configured 3 subgraphQL services as below. Configuration looks like below. Queries and mutations are working fine. But subscriptions are not working. Subgraphs are implemented in c# using hot chocolate.

GraphQL mesh landing page hows spinning wheel ..nothing is flushed out. Sub-graph subscriptions are working fine. I checked that.

\graphql-mesh-docker-master\docker\work.meshrc.yaml

sources:
  - name: accounts
    handler:
      graphql:
        endpoint: http://host.docker.internal:5051/    
        
  - name: inventory
    handler:
      graphql:
        endpoint: http://host.docker.internal:5052/
        
  - name: products
    handler:
      graphql:
        endpoint: http://host.docker.internal:5053/
  
serve:
  hostname: 0.0.0.0

docker logs

am I doing anything wrong ? or

I've got them somewhat working using a souce graph thats using graphql-yoga as a server. I had to explicitely tell the geatway to use SSE like this:

sources:
  - name: Test
    handler:
      graphql:
        endpoint: http://localhost:4010/graphql
        subscriptionsProtocol: SSE

Everything works fine until I hit the "stop" button on GraphiQL. After that the mesh server crashes with the following output:

TypeError: terminated

coming from

node_modules/undici/lib/fetch/index.js:1890
