"Signed fields invalid" for configuring HTTPS transport layer

yes, I have just separated them and it's fine now, but there's 1 more problem about file read exception. I'm following this https://discuss.elastic.co/t/trying-to-set-up-tls-on-elastic-cluster/143323/2 article, and I am trying to find the configuration path of es.path.conf in this helm chart. This path /usr/share/elasticsearch/config/ maybe not the right folder for the read permission although all files here have 777 permission. I've read the log but I haven't found the path. Do you have any idea ?
