Property 'isLoading' does not exist on type 'IntrinsicAttributes & IntrinsicClassAttributes<FormInstance<{}, Partial<ConfigProps<{}, {}>> -Redux form
Redux Form is a very efficient approach for form handling and validation in React + Redux environments. Here the issue you are having looks to be about missing props, and a few interface definitions. I have provided a sandbox at the end.
A solution could be to specify the form interface by yourself, something like this:
export interface FormInterface { handleSubmit: PropTypes.func; handleChange?: PropTypes.func; reset?: PropTypes.func; pristine?: PropTypes.bool; submitting?: PropTypes.bool; error?: PropTypes.bool; invalid?: PropTypes.bool; submitSucceeded?: PropTypes.bool; submitFailed?: PropTypes.bool; anyTouched?: PropTypes.bool;}and use that to derive LoginProps from. Then typescript won't complain about missing props, which is apparently the way redux form works.
See this sandbox for details. I have gone over a few minor stuff for you, as well.
Hope this helps.
