// How come the following snippet's `error` when caught is `undefined`:
app.on('ready', () => {
    Promise.all([......]).then(async () => {
        ...
        const eventRootFolderId = folderIdRegex.exec(event.link)[1];
        ...
    }).catch(error => logger.error(error)); // Undefined
});

// But when I try and catch, and then return the caught error, it is then caught and no longer `undefined`. 

app.on('ready', () => {
    Promise.all([......]).then(async () => {
        ...
        try {
            const eventRootFolderId = folderIdRegex.exec(event.link)[1];
        } catch (innerError) {
            return innerError; // If I change this to something like logger.error(innerError), it also treats innerError to be null, but not when I return it
        }
    }).catch(error => logger.error(error)); // No longer undefined
});
// I was under the assumption that in the first snippet, or any catch block, it catches any error, therefore I don't need to try...catch within the anonymous async function.
