Issue and Reproduction Steps

ERROR TypeError: undefined is not an object (evaluating ‘_reactNative.Text.propTypes.allowFontScaling’) ERROR Invariant Violation: Module AppRegistry is not a registered callable module (calling runApplication). A frequent cause of the error is that the application entry file path is incorrect. This can also happen when the JS bundle is corrupt or there is an early initialization error when loading React Native.

Hello @internationthink and @sarathdb 👋

I’d suggest you to first check your code if you are not using propTypes.allowFontScaling somewhere. If not, maybe you are using some deprecated third-party dependencies that are using these properties ? For example react-native-button or react-native-settings-list are using these deprecated properties and requires a patch as explained here : https://github.com/ide/react-native-button/issues/92

Hope this can give you a hint on how to fix this issue 🙂

Best regards.

PS : you can use a command like grep -R "propTypes.allowFontScaling" * on your project directory to find all occurrences in your code.

In my case, on upgrade RN 0.68.5 to RN 0.69.7, get like error. I solved refacting the property “Text.propTypes.style” to “PropTypes.string” in my app and that’s work’s fine again.

Edit: I didn’t change files of React Native. Just my own files and properties. @karankapur999.

I am also facing the same problem, after upgrade from 0.63.2 to 0.69.4.

Anyone please provide any solution?

@sergiocabreu

could you please share in what all files you changed it ?

karankapur999 on Jan 14, 2023

how you did it ?

It helps me:

Install ‘deprecated-react-native-prop-types’, go to ‘node_modules/react-native-button/Button.js’, import there:

import {TextPropTypes} from ‘deprecated-react-native-prop-types’

Change ‘static propTypes’ to

static propTypes = { … allowFontScaling: TextPropTypes.allowFontScaling, … style: TextPropTypes.style styleDisabled: TextPropTypes.style, … };

And restart the project without cache.

Of course, to save changed dependencies, I advise you to use ‘patch package’: https://www.npmjs.com/package/patch-package
