form submission error intercept

how can I , in a function like this , invoked in a form submission, call set_isLoadingOpen( false ); during a server side error ? //for data manipulation const handleSubmitPostCreate = async (values: FormValues) => { set_isLoadingOpen( true ); await onFinish({ ...values, }); set_isLoadingOpen( false ); };

Hi @DannyWhite. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- To handle server-side errors during form submission, you can use a try-catch block in your handleSubmitPostCreate function. In the catch block, you can call set_isLoadingOpen( false ); to stop the loading state when an error occurs. Here's how you can do it:

const handleSubmitPostCreate = async (values: FormValues) => {
    set_isLoadingOpen( true );

    try {
        await onFinish({
            ...values,
        });
    } catch (error) {
        console.error(error);
        set_isLoadingOpen( false );
    }

    set_isLoadingOpen( false );
};

const handleSubmitPostCreate = async (values: FormValues) => {
    set_isLoadingOpen( true );

    try {
        await onFinish({
            ...values,
        });
    } catch (error) {
        console.error(error);
        set_isLoadingOpen( false );
    }

    set_isLoadingOpen( false );
};

In this function, onFinish is expected to be a promise that resolves when the form submission is successful and rejects when there's a server-side error. If onFinish does not behave this way, you might need to adjust your code accordingly. Also, note that Refine provides out-of-the-box functionality for handling server-side form validation errors with useForm hook. When dataProvider returns a rejected promise with errors field, useForm will automatically update the error state with the rejected errors field. You can refer to the server-side Form Validation documentation (https://refine.dev/docs/advanced-tutorials/forms/server-side-form-validation/) for more information. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

that code does not work. how can I handle a onError status? @kapa.ai that code does not work. how can I handle a onError status?

Let me check the knowledge base for you. One moment! :books: ---------------------- To handle an error status, you can use the onError method provided by Refine's authProvider. This method is called when you get an error response from the API. You can create your own business logic to handle the error such as refreshing the token, logging out the user, etc. Here's an example of how you can use the onError method:

import { AuthProvider } from "@refinedev/core";  
  
const authProvider: AuthProvider = {  
 onError: async (error) => {  
 if (error.status === 401 || error.status === 403) {  
 return {  
 logout: true,  
 redirectTo: "/login",  
 error,  
 };  
 }  
  
 return {};  
 },  
 // ---  
};

import { AuthProvider } from "@refinedev/core";  
  
const authProvider: AuthProvider = {  
 onError: async (error) => {  
 if (error.status === 401 || error.status === 403) {  
 return {  
 logout: true,  
 redirectTo: "/login",  
 error,  
 };  
 }  
  
 return {};  
 },  
 // ---  
};

In this example, if the error status is 401 or 403, the user will be logged out and redirected to the login page. You can also use the useOnError hook to handle errors in a unified way. When an error is thrown by any data hook, the useOnError function is triggered with the error object. Here's an example:

import { useOnError } from "@refinedev/core";  
  
const { mutate: onError } = useOnError();  
  
fetch("<http://example.com/payment">)  
 .then(() => console.log("Success"))  
 .catch((error) => onError(error));

import { useOnError } from "@refinedev/core";  
  
const { mutate: onError } = useOnError();  
  
fetch("<http://example.com/payment">)  
 .then(() => console.log("Success"))  
 .catch((error) => onError(error));

In this example, if the payment request is declined by the API, the onError function will be triggered. For more information, you can refer to the useOnError (https://refine.dev/docs/authentication/hooks/use-on-error/) and onError (https://refine.dev/docs/authentication/auth-provider/#onerror) documentation. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai no. i'm using useForm. how can i setup a onError function ?

kapa.ai•2y ago

Let me check the knowledge base for you. One moment! :books: ---------------------- In the useForm hook provided by Refine, you can handle errors using the onMutationError callback function. This function will be called after a mutation fails. Here's an example of how you can use it:

useForm({  
 onMutationError: (data, variables, context, isAutoSave) => {  
 console.log({ data, variables, context, isAutoSave });  
 set_isLoadingOpen( false );
 },  
});

useForm({  
 onMutationError: (data, variables, context, isAutoSave) => {  
 console.log({ data, variables, context, isAutoSave });  
 set_isLoadingOpen( false );
 },  
});

In this example, onMutationError is called with the returned value from useCreate or useUpdate (depending on the action), the variables passed to the mutation, the react-query context, and a boolean value indicating whether the mutation was triggered by the auto-save feature or not. When an error occurs, set_isLoadingOpen( false ); is called to stop the loading state. For more information, you can refer to the useForm documentation (https://refine.dev/docs/data/hooks/use-form#onmutationerror). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai no way. the code does not work

kapa.ai•2y ago

Let me check the knowledge base for you. One moment! :books: ---------------------- I apologize for the confusion. The useForm hook in Refine does not directly provide an onError or onMutationError callback. However, you can handle errors in the onFinish function that you pass to your form. Here's how you can modify your handleSubmitPostCreate function to handle errors:

const handleSubmitPostCreate = async (values: FormValues) => {
    set_isLoadingOpen( true );

    try {
        await onFinish({
            ...values,
        });
    } catch (error) {
        console.error(error);
        set_isLoadingOpen( false );
        // Handle the error here
        return;
    }

    set_isLoadingOpen( false );
};

const handleSubmitPostCreate = async (values: FormValues) => {
    set_isLoadingOpen( true );

    try {
        await onFinish({
            ...values,
        });
    } catch (error) {
        console.error(error);
        set_isLoadingOpen( false );
        // Handle the error here
        return;
    }

    set_isLoadingOpen( false );
};

In this function, onFinish is expected to be a promise that resolves when the form submission is successful and rejects when there's a server-side error. If onFinish does not behave this way, you might need to adjust your code accordingly. If you're using a data provider for your API calls, Refine expects errors to be extended from HttpError. You can implement error handling in your data provider as shown in the Error Format section of the Data Provider documentation (https://refine.dev/docs/data/data-provider#error-format). If you're still having trouble, could you please provide more details about your onFinish function and how you're handling your API calls? This will help me give you a more accurate answer. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
