There is an error "Unable to load PFX certificate" when connecting the aws elasticsearch.

I tested with my ec2 and aws elasticsearch but got the errors.
How can I gernerate logs without an error below?

makelogs - url https://search-xxxxx-es-fd5uuxxxxx3dvjjshurlfuwn4fq.ap-northeast-2.es.amazonaws.com/

node:internal/tls/secure-context:278
context.loadPKCS12(toBuf(pfx));
