http://mercure.preprod.oryx-immobilier.com/.well-known/mercure

In your case actually this is not an error. This is a warning from react native.

componentWillReceiveProps is a synchronous hook. Calling asynchronous function like data fetching inside this hook will need to render in between when the new props are set and when data has finished loading.

Thus, componentWillReceiveProps is being deprecated in favor of the following reason:

1. Use componentDidUpdate

So, I suggest you to use componentDidUpdate hook as far as possible and update your code.

• The similar things happen when comparing componentWillMount and componentDidMount. Use componentDidMount whenever you need operate async operation and forget componentWillMount at all condition.
