There have been several posts about YUP Validation not working correctly for that video topic. Is there any solution to this error because I just ran into this error by reaching the YUP Validation topic on the React Native course. @Mosh

For everyone who wants the answer to this. You must change "onChange attribute in the AppTextInput to onChangeText.

Example:

```auto
<AppTextInput
              autoCapitalize="none"
              autoCorrect={false}
              icon="email"
              keyboardType="email-address"
              onChangeText={handleChange("email")}
              placeholder="Email"
              textContentType="emailAddress"
            />

```
