Interestingly, this doesn't happen on edge functions.

Same here on vercel using an endpoint like so:

import { google } from 'googleapis'

export async function get({ params }) {

    const oauth2Client = new google.auth.OAuth2(
       ......
    );

    const scopes = [
        'https://www.googleapis.com/auth/calendar.events.freebusy',
        'https://www.googleapis.com/auth/calendar.events.owned',
        'https://www.googleapis.com/auth/userinfo.email'
    ];

    const authorizationUrl = oauth2Client.generateAuthUrl({
        access_type: 'offline',
        scope: scopes,
        include_granted_scopes: true
    });

    return new Response(JSON.stringify({login: authorizationUrl}), {
        status: 200,
        headers: {
            "Content-Type": "application/json",
            "Access-Control-Allow-Origin" : "*"
        }
    });
}

The error is the same:

ERROR   Unhandled Promise Rejection     {"errorType":"Runtime.UnhandledPromiseRejection","errorMessage":"TypeError [ERR_INVALID_ARG_TYPE]: The \"chunk\" argument must be of type string or an instance of Buffer or Uint8Array. Received an instance of ArrayBuffer"

@pilcrowOnPaper have you tried in the newest version? If so I can take a look. Also what version of Node are you using on Vercel?

marcfielding1 commented 1 year ago

For me it's ^1.6.10, node 18 - I'm not sure it's astro it's probably the vercel adaptor which for me is ^2.3.2 .

pilcrowOnPaper commented 1 year ago

@matthewp

No issue with astro@1.6.15 and @astrojs/vercel@2.3.6, both on Node v 16.x and 18.x.

marcfielding1 commented 1 year ago

Hey, really? I shall test it now!

matthewp commented 1 year ago

@pilcrowOnPaper thanks for testing it.

@marcfielding1 please report back what you find!

marcfielding1 commented 1 year ago

@matthewp You tested this with an async handler? My initial results show the same problem, lemmy double check when I get home.(2 hours)

matthewp commented 1 year ago

@marcfielding1 what did you find?

matthewp commented 1 year ago

Closing as this issue is stale. Please file a new issue if you still see the same problem.
