Clients page: Failed to fetch clients. undefined

[elpablos]

Description
If I open in administration "Clients" overview page it fails on:
Failed to fetch clients. undefined

Problem
I have find out that on request works correctly:

Request URL:  /api/seacat_auth/client?p=1&i=20&f=
Request Method: GET
Status Code: 200

And the difference against localhost is that status code didn't return "200 OK" but only "200".
In a code, I have find out that there is the "statusText" check which is failing.

See HTTP response status codes for a list of codes and their associated status messages. Note that HTTP/2 does not support status messages.

see https://developer.mozilla.org/en-US/docs/Web/API/Response/statusText

Solution:

Drop response.statusText and use response.status as solution.

see axios/axios#1501

DoD

• replace statusText check with status
