Question: I'm building out CRUD functionality and create had worked the other day with the same code in the component, but now it is giving an error:

*Unhandled Rejection (TypeError): Cannot read properties of undefined (reading 'data')*

I'm getting an error with the validations, and not sure if it has to do with props. Here is the code where the error exists:

```
> 30 |     const errorResponse = err.response.data.errors;
 console.log(errorResponse)
     | ^  31 |     const errorArr = [];
  32 |     for (const key of Object.keys(errorResponse)) {
  33 |         errorArr.push(errorResponse[key].message)```

Is anyone familiar with this issue and knows how to fix it?

Answer: 
You trying to read data of object that doesn't exist.

```
err.response.data

```

Try to `console.log(err)` and `console.log(err.response)` You will probably see that you have something wrong in your response.
The problem may come from the URL that connects the API to the application, for this the data is not retrieved from the database
