Kibana crash because ["publicBaseUrl" is not allowed

[knitehias]

Hello,

I am building my own kibana image from debian. The image looks ok.
But when I run my elasticsearch and kibana in kubernetes, kibana crashed due to
FATAL ValidationError: child "server" fails because ["publicBaseUrl" is not allowed]

I am on 7.5.2 of kibana.
My configuration is like
server:
host: "0.0.0.0"
publicBaseUrl: https://kibana.knitehais.network

elasticsearch:
...

Best Regards,
Sai
