HTTP 400 error on https://api.hubapi.com/contacts/v1/lists/all/contacts/all

contacts

#1

We need to fetch all contact properties.
Until recently (the past couple weeks),
fetching the list of contact props and supplying each one in the list url was working fine…
However today, it seems an astronomical number of new properties have been added in the system, and now this method of supplying all props in the listing url no longer works, ie the url is over 9K chars long and is getting HTTP 400…
Can you please implement a property=all feature or similar, so property blacklists (tried that, but new props keep showing up) or multiple api calls with different property sets aren’t needed.
tks.
