App development OAuth, internal server error

When sending an OAuth request:

monday.com: Where Teams Get Work Done&state=&app_version_id=

When clicked the Authorize button:

A post was sent to

https://kpmg356.monday.com/oauth2/authorized
with payload (I’ve removed the tokens):
oauth_csrf_token:
oauth_payload_token:
app_permissions: {“isEnabled”:false,“type”:“workspaces”,“permittedIds”:}

Then I received the callback with an error response:

my_url_at.us.monday.app/monday/callback?error=server_error&error_description=Internal+server+error&state=the_same_state

any idea how to fix this?
