sentry-react-native: Sourcemaps not working (Metro bundler)

We’re at the 3rd attempt right now to get Sentry sourcemaps working for using expo export --platform web, which is running Metro bundler for web.

The screenshot below is a result from running sentry-cli sourcemaps explain <eventId>

This is our setup:

package.json > scripts

        "exportWeb": "expo export --platform web --dump-sourcemap",
        "uploadWebSourceMaps": "export EXPO_PUBLIC_SENTRY_RELEASE=web@$(git rev-parse HEAD); node ./scripts/uploadWebSourceMaps.js",

Our CI/CD triggers npm run exportWeb && npm run uploadWebSourceMaps

This is uploadWebSourceMaps.js

// Inspired by @see https://github.com/getsentry/action-release/

const path = require('path');

const dotenv = require('dotenv');
dotenv.config();

const { getJsonFileContent, checkEnvVars } = require('./utils/cli');
const { DIST_PATH } = require('./utils/paths');
const { createReleaseAndUploadSourcemaps } = require('./utils/sentry/cli');

const METADATA_PATH = path.resolve(DIST_PATH, 'metadata.json');

async function main() {
    checkEnvVars([
        'EXPO_PUBLIC_SENTRY_ENVIRONMENT',
        'EXPO_PUBLIC_SENTRY_ORG',
        'EXPO_PUBLIC_SENTRY_PROJECT',
        'SENTRY_AUTH_TOKEN',
    ]);

    process.env['SENTRY_ORG'] = process.env.EXPO_PUBLIC_SENTRY_ORG;
    process.env['SENTRY_PROJECT'] = process.env.EXPO_PUBLIC_SENTRY_PROJECT;
    process.env['SENTRY_ENVIRONMENT'] = process.env.EXPO_PUBLIC_SENTRY_ENVIRONMENT;
    process.env['SENTRY_RELEASE'] = process.env.EXPO_PUBLIC_SENTRY_RELEASE;

    const metadata = await getJsonFileContent(METADATA_PATH);
    const bundleFileName = metadata.fileMetadata.web.bundle;
    const bundlePath = path.resolve(DIST_PATH, bundleFileName);

    await createReleaseAndUploadSourcemaps({
        bundlePath,
    });
}

void main();

This is utils/sentry/cli.js

const SentryCli = require('@sentry/cli');

const { checkEnvVars } = require('../cli');

let _cli;

function getCli() {
    process.env['SENTRY_PIPELINE'] = 'rocko';

    if (!_cli) {
        _cli = new SentryCli().releases;
    }

    return _cli;
}

async function createReleaseAndUploadSourcemaps({ bundlePath }) {
    checkEnvVars(['SENTRY_ORG', 'SENTRY_PROJECT', 'SENTRY_ENVIRONMENT', 'SENTRY_RELEASE', 'SENTRY_AUTH_TOKEN']);

    const cli = getCli();
    const version = process.env['SENTRY_RELEASE'];
    await cli.new(version, {
        projects: [process.env.EXPO_PUBLIC_SENTRY_PROJECT],
    });

    await cli.setCommits(version, {
        auto: true,
    });

    await cli.uploadSourceMaps(version, {
        include: [bundlePath],
    });

    await cli.newDeploy(version, {
        env: process.env['SENTRY_ENVIRONMENT'],
    });

    await cli.finalize(version);
}

module.exports = {
    getCli,
    createReleaseAndUploadSourcemaps,
};

Any help / advise would be great.
