Connection failed Max number of 100 subscriptions reached

Dear Support Team

I am using AWS Amplify in my React Native mobile app and Web app, they are real time app and they need to change data many times in short time, using GraphQL with Subscription Method

At the beginning everything works fine but after seconds It drops and get me an error message

"Connection failed: {\"errors\":{\"errorType\":\"MaxSubscriptionsReachedError\",\"message\":\"Max number of 100 subscriptions reached\"}}"

and sometimes it shows me another error like websocket is unconnected

My question

What should I do to get unlimited subscription requests ?

thank you!

Dear @chrisbonifacio

I already fixed the problem

The code was:

  useEffect(() => {
    //update when inService go to the next call
    API.graphql({
      query: subscriptions.onChangeInService,
      authMode: "AWS_IAM",
    }).subscribe({
      next: ({ provider, value }) => {
           // my code ...
      },
      error: (error) => console.log("update inservice ", error.error.errors[0]),
    });
  }, []);

and the solution was adding .unsubscribe(); like this:

 useEffect(() => {
    const changeInservice = API.graphql({   //  <== add const changeInservice 
      query: subscriptions.onChangeInService,
      authMode: "AWS_IAM",
    }).subscribe({
      next: ({ provider, value }) => {
         // my code ...
      },
      error: (error) => console.log("update inservice ", error.error.errors[0]),
    });

    return () => changeInservice.unsubscribe();    // <== add this one
  }, []);

⚠️ I find the solution in these sources : ⚠️ video: https://www.youtube.com/watch?v=HZUlQ7Z2xHQ&t=2154s AWS awmplify docs: https://docs.amplify.aws/lib/graphqlapi/subscribe-data/q/platform/js#using-amplify-graphql-client

Thank you Sir for your answer

Awesome! I had a feeling it might’ve been the side effect cleanup lol

Thank you for the update and glad we could help! Enjoy the rest of your day, sir 😄
