Typeerror: cannot read properties of null (reading ‘useref’)

TypeError: Cannot read properties of null (reading ‘useRef’)

This error occurs when you are trying to access a property or method on a null value or object.

In the specific case of ‘useRef’, which is a hook provided by React, this error indicates that you are trying to access the ‘useRef’ property on an object which is null, causing the TypeError.

Here is an example to illustrate this error:

<script type="text/javascript">
  import React, { useRef } from 'react';

  function MyComponent() {
    const refValue = useRef(null);
    console.log(refValue.current.useref);
  }

  export default MyComponent;
  </script>

In the above example, we are trying to access the ‘useref’ property of the ‘current’ property of the ‘refValue’ object, which is set to null. This results in a TypeError since null does not have a ‘useref’ property.

To fix this error, ensure that you are correctly initializing the ‘useRef’ object with a non-null value. You can initialize it with any value, for example:

<script type="text/javascript">
  import React, { useRef } from 'react';

  function MyComponent() {
    const refValue = useRef("initialValue");
    console.log(refValue.current.useref);
  }

  export default MyComponent;
  </script>

In the corrected example, ‘refValue’ is initialized with the string “initialValue” instead of null. Now, the TypeError will not occur since ‘refValue.current’ is an object that has the ‘useref’ property.
