I am trying to prevent any error thrown from my server crash the browser. I have tried with try-catch but also with the apollo-link-error's onError Link. The behaviour I am looking for is , instead of crashing the app , display something from my client. What I have tried:

onSubmit={(values)=>
          try{
logIn({variables:{"name":values.name,"email":values.email}})
}catch(err){
return (err)
}


if(error) return <p>An error occured</p>

But also with apollo-link-error:

const errorLink=onError(({graphQLError,networkError})=>{
   if(graphQLError){
    return "There was a problem"
}
}

The errorLink only does throw this error in my console , but it does not also present the behaviour I had hoped: prevent the app from crashing. Could you please let me know what to do?
