Arcade Oauth callback endpoint throwing 500's

[davedodea]

I'm attempting to authorise the Notion toolkit. I have a custom Notion provider in place and I have set up a the customer verifier endpoint in my app via the Arcade dashboard.

1. User clicks authorize for the Notion toolkit - app redirects to:
   https://www.notion.so/install-integration?response_type=code&client_id=24dd872b-594c-8056-b0a7-00373f87b16d&redirect_uri=https%3A%2F%2Fcloud.arcade.dev%2Fapi%2Fv1%2Foauth%2Ff4c6b_ap_XpDsNFgo5Hmr%2Fcallback&state=877f76fd-b5de-47aa-9793-65e940a38cf2&owner=user

2. User confirms scopes, gets redirected to:
   https://cloud.arcade.dev/api/v1/oauth/callback_verify?flow_id=877f76fd-b5de-47aa-9793-65e940a38cf2
   This cal throws a 500 with:

{
"code": 500,
"msg": "Internal server error",
"data": null
}

Any thoughts or more info I can share to debug?

Hi @davedodea, thanks for your patience!
I've fixed a number of subtle bugs in this flow. Is this still happening for you?
