[helm] Authentication doesn't work with 1.5.5 version

### Helm Chart Version

1.5.5

### What step the error happened?

Upgrading the Platform or Helm Chart

### Relevant information

When trying to authenticate and login to the Webapp, we're getting Error 500 (attached log below).

Our Ingress configuration looks like this (the part responsible for API calls):
`
- backend:
service:
name: {{ .Chart.Name }}-airbyte-server-svc
port:
number: 8001
path: /api
pathType: Prefix
`

We've also tried using path as a `/` and `/api/v1/applications/token` with Exact path - same result. Maybe we're missing something in the configuration?
