Custom Database Script for Posgres

We are using a Custom database script to log in and register for our development. We are currently connecting Postgres DB for that. It was working fine, but suddenly it stopped working and now it is giving me an error. The sample error is given below API give status code 400 and error
{“error”:"[Error] Unknown authenticationOk message typeMessage { name: ‘authenticationOk’, length: 23 }",“console”:,“fromSandbox”:true}

I am having the same issue.
It looks like we should upgrade pg client but I don’t know how on auth0.
