Clarification on how to use onSuccess / onError with mutation

[cn-johndpope]

is it possible to pass this into the given mutations?

wanting to do something like this.... at client level - without rewriting sdk

https://github.com/c121914yu/FastGPT/blob/8c70205940138c75e48fa648b927fafeea1f0e5a/src/hooks/useRequest.tsx

this runs / authenticates fine - but I need to save the token to add to auth header.

           var model:UserLoginModel = {}
            model.userName = username
            model.password = password
            await postMutation.mutate(model)

this code compiles and runs - but I don't see any onSuccess callback.

           var model:UserLoginModel = {}
            model.userName = username
            model.password = password
            await postMutation.mutate(model,{
                onError: (error:any, variables:any, context:any) => {
                    // An error happened!
                    console.log(`🔥 error ${error}`)
                  },
                  onSuccess: (data:any, variables:any, context:any) => {
                    console.log("🎸  data:",data)
                    console.log("variables:",variables)
                    console.log("context:",context)
        
                    // let token = data.token
                    // axiosInstance.defaults.headers.common.Authorization = `Bearer ${token}`;
                    // Boom baby!
                  },
            })

// here we are authenticated - but in the body of response - there's a token
the body - is by default undefined - so there's no token - auto populated...
console.log("🌱 success result:",postMutation)
console.log("🌱 success result:",postMutation.result.token ?? "") // FAILS - as the postMutation . data = undefined

🌱 success result: {"context": undefined, "data": undefined, "error": null, "failureCount": 0, "failureReason": null, "isError": false, "isIdle": true, "isLoading": false, "isPaused": false, "isSuccess": false, "mutate": [Function anonymous], "mutateAsync": [Function bound mutate], "reset": [Function bound reset], "status": "idle", "variables": undefined}

can tanstack be made to default to any - instead of undefined?

This seems unrelated to Rapini. For general support for Tanstack please file issues in their repo. For axios issues file an issue in the axios repo. Thanks
