I have the following issue:

After integrating withSentryConfig in the metro.config.js, annotateReactComponents is true, we found that when building iOS application through Xcode in debug mode, the .sentry/. defaultBabelTransformerPath file was first created and then deleted before the build was completed. However, when loading the JS Bundle, sentry tried to read the file again and threw an error.

Actual result:

Expected result:

no error

if i comment this line. There is no error but the file can not be deleted automatically.

function withSentryBabelTransformer(config) {
    const defaultBabelTransformerPath = config.transformer && config.transformer.babelTransformerPath;
    utils_1.logger.debug('Default Babel transformer path from `config.transformer`:', defaultBabelTransformerPath);
    if (!defaultBabelTransformerPath) {
        // This has to be console.warn because the options is enabled but won't be used
        // eslint-disable-next-line no-console
        console.warn('`transformer.babelTransformerPath` is undefined.');
        // eslint-disable-next-line no-console
        console.warn('Sentry Babel transformer cannot be used. Not adding it...');
        return config;
    }
    if (defaultBabelTransformerPath) {
        (0, sentryBabelTransformerUtils_1.saveDefaultBabelTransformerPath)(defaultBabelTransformerPath);
        process.on('exit', () => {
             // comment this line
            // (0, sentryBabelTransformerUtils_1.cleanDefaultBabelTransformerPath)();
        });
    }
    return Object.assign(Object.assign({}, config), { transformer: Object.assign(Object.assign({}, config.transformer), { babelTransformerPath: require.resolve('./sentryBabelTransformer') }) });
}
