I have a rather long query on my gql server, the resolver calls a grpc method. when I run this locally it works, but when I make the query on our development deployment(https) the request comes back with
<html><head>
<meta http-equiv="content-type" content="text/html;charset=utf-8">
<title>502 Server Error</title>
</head>
<body text=#000000 bgcolor=#ffffff>
<h1>Error: Server Error</h1>
<h2>The server encountered a temporary error and could not complete your request.<p>Please try again in 30 seconds.</h2>
<h2></h2>
</body></html>
There are other grpc calls that work, over https as well. So I don't think it is any issue there..
In the gcp logs I can actually see the result from the resolver logged. although in the browser it comes as a 502 error.
my resolver
train: async (parent, args) => {
const { projectId, yml } = args
let result = await nluTrain(projectId, yml);
return { done:result }
}
my server
const server = new ApolloServer({
typeDefs: schema,
resolvers,
context: async ({ req, connection}) => {
if(req){
return {
req,
};
}
},
});
server.applyMiddleware({ app, path: '/graphql' });
const httpServer = http.createServer(app);
server.installSubscriptionHandlers(httpServer);
httpServer.listen({ port: 8001 }, () => {
console.log('Apollo Server on http://localhost:8001/graphql');
});
