Add:
"type": "module",
To the repository’s root level package.json
file.
Now instead of
exports.handler = async (event, context, callback) => {
}
use this:
export async function handler(event, context) {
}
And any time you used
callback(null, {
statusCode: 200,
body: html,
})
Now use
return {
statusCode: 200,
body: html,
}
