Troubleshooting

“MediapipePosedetection TurboModule is not available”

The native module isn’t in your build, or the New Architecture is off.

1. Confirm the New Architecture is enabled (newArchEnabled=true on Android; default on React Native 0.76+ and Expo SDK 52+).
2. If you’re on Expo, make sure you’re running a development build, not Expo Go.
3. Do a clean native rebuild: npx expo prebuild --clean on Expo, or cd ios && pod install plus cd android && ./gradlew clean on bare React Native.

“Failed to initialize posedetection plugin”

The VisionCamera frame processor plugin couldn’t be registered. Usually one of:

• react-native-worklets-core isn’t installed, or its Babel plugin is missing from babel.config.js.
• Metro is serving an old bundle. Restart with npx expo start --clear or npx react-native start --reset-cache.

“Failed to create detector”

MediaPipe couldn’t load the model.

1. Check the file name you pass matches the bundled file exactly, including .task.
2. Check the file is actually in the build. See Model files.
3. On Expo, re-run npx expo prebuild --clean after adding a model.
4. Make sure it’s a pose landmarker model, not a different MediaPipe task.

Camera shows but onResults never fires

• Did you attach the frame processor? With your own <Camera>, pass frameProcessor={solution.frameProcessor}.
• If you use your own <Camera>, set pixelFormat="rgb", which is what MediapipeCamera uses and what the library is tested with.
• Check that camera permission was granted.
• Add an onError callback and log what it receives.

Landmarks are offset or flipped

You’re probably drawing normalized coordinates directly. Convert them with the ViewCoordinator passed to onResults, and wire up all the camera handlers. See Drawing a skeleton overlay.

Memory warnings or crashes during long sessions

1. Update to the latest version.
2. Set fpsMode to 10–15.
3. Keep numPoses: 1 and shouldOutputSegmentationMasks: false.
4. Try Delegate.CPU on devices with limited GPU memory.

Upgrading from an old-architecture version

The JavaScript API is the same. Upgrade React Native to 0.74+, enable the New Architecture, and do a full clean rebuild of both platforms.
