Meteor updated to 2.3.1, WebApp.connectHandlers no longer recognizing body?

I have a project working with a 3rd party API that has been in use with the following code:


WebApp.connectHandlers.use('/deletion', (req, res) => {

    if(req.method == "POST") {

        Event.process(
            req.body,
            req.headers[constants.X_E_SIGNATURE],
            config,
            environment
        ).then((responseCode) => {

This had worked properly before update, and now after update, it seems that req.body is undefined.

Anything I should know of that changed between versions which would prevent this from functioning?

First thing to always check is the changelog:

That said, v2.3 was Node 14 upgrade so that might have changed something for you.
