tls: failed to find any PEM data in certificate input

[krishR007]

"tls": {
    "server_cert": "/etc/certs/server/tls.crt",
    "server_key": "/etc/certs/server/tls.key"
  }

Can you tell me how to host TLS file in kubernets using helm cause i'm facing issue failed to find any PEM data in certificate input while installing this repo using helm ?
