fix: TypeError cannot read properties of undefined (reading 'data') (#9766)

# Pull Request Template

## Description

**Issue**
The error `Cannot read properties of undefined (reading 'data')` occurs
because the `error.response.data` is accessed without checking if
`error.response` is present.

I can able to reproduce this issue.

**Solution**
To resolve this issue, I can add a check to ensure that this
`error.response` is defined before accessing the `error.response.data`
