onError handler in custom baseQuery

[abhieshekumar]

Hi, the current behaviour is that the onError callback is executed each time after a retry fails.

query:() => ({
  url: API_PATH,
  method: "GET",
  // execute once all retries have failed too. Right now it is getting executed for each retry
  onError: ()=>{
    showNotification(ERROR);
  }
})
extraOptions: { maxRetries: NUMBER },

Is there a recommended approach to only execute the callback once all the retries have failed?

There is no such thing as an onError callback in RTK Query. I'm honestly a bit confused right now. Are you using a custom baseQuery?

[abhieshekumar]

my bad, yes it's a custom baseQuery.

My advice would be not to have it be part of your baseQuery, because retry wraps around that - it cannot look inside. Use the onQueryStarted lifecycle event instead, you can handle errors there.
