I already remove all rules & hooks, but still get this error when signup: Request URL: https://[tenant].au.auth0.com/dbconnections/signup Request Method: POST Status Code: 400 Remote Address: 104.18.236.45:443 cf-request-id: 07e005f81f0000c6b8b3ba4000000001

To follow up, we were able to find the solution in a DM conversation! The “Cannot read property ‘0’ of undefined” was thrown because of a custom DB get-users script. Updated a line from user = body.items[0] to user = body.items.length && body.items[0]

Error: cannot POST https://[tenant].au.auth0.com/dbconnections/signup (400)

I see, “Cannot read property ‘0’ of undefined”… Are you using Universal Login? Also, what SDK are you using?
