Hi all,
I recently upgraded my project from React Native 0.72.2 to React Native 0.81.0.
With RN 0.72.2 the Dynatrace React Native plugin worked fine, but after upgrading, the app crashes immediately on startup with the following error:
Error:
Render Error
Cannot call a class as a function
Source (Touchables.js:45:23):
exports.Text = (_d = class Text extends ReactNative.Text {
},
_d._dtInfo = { type: Types_1.Types.Text },
_d);
Component Stack:
<Text /> Touchables.js:45
<AppText /> AppText.tsx:13
<ScrollView /> ScrollView.js:730
<ErrorFallback /> ProvidersWrapper.tsx:74
<ErrorBoundary /> react-error-boundary.js:11
<SafeAreaProvider /> SafeAreaContext.tsx:35
<Provider /> react-redux.legacy-esm.js:910
<View_withRef /> View.js:28
...
babel.config.js
module.exports = {
presets: ['module:@react-native/babel-preset'],
plugins: [
[
'@babel/plugin-transform-react-jsx',
{
runtime: 'automatic',
importSource: '@dynatrace/react-native-plugin',
},
],
['react-native-reanimated/plugin'],
],
};
metro.config.js
const { getDefaultConfig, mergeConfig } = require('@react-native/metro-config');
const config = {
transformer: {
babelTransformerPath: require.resolve(
'@dynatrace/react-native-plugin/lib/dynatrace-transformer',
),
},
reporter: require('@dynatrace/react-native-plugin/lib/dynatrace-reporter'),
};
module.exports = mergeConfig(getDefaultConfig(__dirname), config);
dynatrace.config.js
module.exports = {
react: {
debug: true,
autoStart: false,
errorHandler: {
enabled: true,
reportFatalErrorAsCrash: true,

},
capture: { networkRequests: true },
android: {
enabled: true,
config: `

}
}
`,
},
ios: {

config: `
<key>DTXAutoStart</key>

},
};
Solved! Go to Solution.

Hi,
We are aware of the issue. Solution is internally already working and will be released ASAP.
RN 0.81 changed the Text which is breaking the instrumentation for those parts.
