Function APISubmitAction

APISubmitAction(
__namedParameters: APISubmitActionProps,
): Promise<Object | Response>
React Router route action handler used to submit form data to a backend endpoint (typically a Django REST Framework API). The function processes submitted FormData, extracts the serialized formState, and constructs a payload object suitable for API submission.

This action expects the form submission to include a field named formState containing a JSON serialized object representing the client-side form state.

The action also reads other standard form fields such as tz (timezone) and merges them with the parsed formState.
Parameters
- __namedParameters: APISubmitActionProps
Returns Promise<Object | Response>
Throws
Error Throws if the formState field is missing or cannot be parsed as JSON.
Example
```
Form submission must include a serialized form state:

<Form method={method}>
  <input type="hidden" name="formState" value={JSON.stringify(formState)} />
  <input type="hidden" name="metadata" value={JSON.stringify(metadata)} />
  <input type="hidden" name="tz" value={timezone} />
</Form>
```
Example
```
Basic usage inside a React Router route definition:

{
  path: "/:module/:id",
  action: APISubmitAction
}
```
