Hi @mauryo. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:
----------------------
To handle errors in the
useRegister
hook and show them in the input fields, you can follow the approach outlined in the provided knowledge sources. Since the authProvider
methods always return a resolved promise, you need to handle errors using the success
value in the response.
Here's a step-by-step guide to achieve this:
1. Import and Use useRegister
Hook: Import the useRegister
hook from @refinedev/core
.
2. Handle the Registration Process: Use the mutate
function from the useRegister
hook to handle the registration process.
3. Check for Errors: In the onSuccess
callback, check if the success
value is false
. If it is, handle the error accordingly.
4. Display Errors in Input Fields: Use state to manage and display error messages in the input fields.
Here is an example implementation:
Explanation:
- Form Setup: The form is created using Ant Design components.
- State Management: The errors
state is used to store and display error messages.
- Error Handling: In the onSuccess
callback of the register
function, if data.success
is false
, the error messages are set in the errors
state.
- Displaying Errors: The validateStatus
and help
properties of Form.Item
are used to display error messages.
For more details, you can refer to the useRegister documentation (https://refine.dev/docs/authentication/hooks/use-register/#error-handling).

@kapa.ai if i use typescript, whitch is the type for the error?
Let me check the knowledge base for you. One moment! :books:
----------------------
When using TypeScript, you can define the type for the error based on the
HttpError
type provided in the knowledge sources. The HttpError
type is defined as follows:
You can use this type to type the error in your component. Here is how you can integrate it into the previous example:
Explanation:
- Type Definition: The HttpError
type is defined and used to type the errors
state.
- State Management: The errors
state is typed as Partial<HttpError>
to allow for partial updates.
- Error Handling: The error from the onSuccess
callback is cast to HttpError
before setting it in the state.
For more details, you can refer to the HttpError documentation (https://refine.dev/docs/core/interface-references/#httperror).
