Kibana fails login,commands with ERROR

Hello i was configuring minimal security for Elasticsearch following the docs bellow.

I set a password , but the problem is Kibana fail to login.

You will find a screenshot of the error :

Hi @The-morpho ,

It looks like your password is a number, but Kibana expects a string. If the password consists of only numbers try to enclose it in quotes:

elasticsearch.password: "12345678"

Best,
Oleg
