How to setup Sentry-cli source maps with react-native

Question

Introduction

Hi, I'm trying to get Sentry to recognise our sourcemaps in a react-native project, but I can't get it working.

The artifacts are uploading - I can see them in the WebUI, but the events lack context/mapping:

Question

Can anyone see any problems in my setup?

Thanks!

 Background

Assumptions

• uploading release artifacts, then deleting artifacts from web ui, then re-uploading new artifacts is valid
• "abs_path": "app:///index.bundle", requires the bundled js needs to be renamed to index.bundle
• That fact that all events have a processing error: Discarded invalid parameter 'dist' should not effect sourcemaps
• Once everything lines up, all my historical events for the release will benefit from the uploaded files/sourcemaps

Xcode build phase

During the XCode build phase we already bundle the DSym.

In this script, I'm trying to pull out the bundled js and sourcemap, and uploading it.

Script

#!/bin/bash
# WARNING: Run directly from Xcode

# For testing of Xcode bundling/sentry locally, set to "true"
DEBUG_FORCE_BUNDLING="true"

printf "Xcode: Bundle react-native and upload to Sentry"

source ../scripts/xcode/utils/node_activate.sh

# Create bundle and sourcemap
export NODE_BINARY=node
export SENTRY_PROPERTIES=sentry.properties
DEST=$CONFIGURATION_BUILD_DIR/$UNLOCALIZED_RESOURCES_FOLDER_PATH
export EXTRA_PACKAGER_ARGS="--sourcemap-output $DEST/main.bundle.map.js";
if [ "${CONFIGURATION}" = "Release" ]; then
    FORCE_BUNDLING="$DEBUG_FORCE_BUNDLING" \
    ../node_modules/@sentry/cli/sentry-cli react-native xcode \
    ../node_modules/react-native/scripts/react-native-xcode.sh
else
   FORCE_BUNDLING="$DEBUG_FORCE_BUNDLING" \
   ../node_modules/@sentry/cli/sentry-cli react-native xcode \
   ../node_modules/react-native/scripts/react-native-xcode.sh
fi

# Copy bundle & sourcemap
mkdir -p ../.xcodebuild
cp $DEST/main.jsbundle ../.xcodebuild/index.bundle # rename?
cp $DEST/main.bundle.map.js ../.xcodebuild
echo "Size of file $(wc -c ../.xcodebuild/index.bundle)" # RENAME!?
echo "Size of sourcemap $(wc -c ../.xcodebuild/main.bundle.map.js)"

# Upload sentry release
# https://docs.sentry.io/cli/releases/#creating-releases
APP_IDENTIFIER="com.mycompany.app"
VERSION="1.4.21"
RELEASE_NAME="$APP_IDENTIFIER-$VERSION"
DISTRIBUTION_NAME="2400"

function sentry_release {
    npx sentry-cli releases \
        files $RELEASE_NAME \
        $1 $2 $3
        --dist $DISTRIBUTION_NAME \
        --strip-prefix ".build" \
        --ignore node_modules \
        --rewrite "$(pwd)"

}

sentry_release upload ../.xcodebuild/index.bundle '~/index.bundle'
echo "sentry_release upload"

sentry_release upload-sourcemaps ../.xcodebuild/main.bundle.map.js
echo "sentry_release upload-sourcemaps"

echo `date`
echo "DONE"

Note: The important bit of node_modules/react-native/scripts/react-native-xcode.sh is:

BUNDLE_FILE="$DEST/main.jsbundle"

echo "BUNDLE_FILE: $BUNDLE_FILE" > ~/bh/react-native-native/bundle.log

"$NODE_BINARY" $NODE_ARGS "$CLI_PATH" $BUNDLE_COMMAND \
  $CONFIG_ARG \
  --entry-file "$ENTRY_FILE" \
  --platform ios \
  --dev $DEV \
  --reset-cache \
  --bundle-output "$BUNDLE_FILE" \
  --assets-dest "$DEST" \
  $EXTRA_PACKAGER_ARGS

After MONTHS, we realised we had to write client code to knit in the Distribution and Release....

    const configureSentry = () => {
        Sentry.config(config.sentry.dsn).install();
        Sentry.setDist(DeviceInfo.getBuildNumber());
        Sentry.setRelease(DeviceInfo.getBundleId() + '-' + DeviceInfo.getVersion());
    };
