When running custom dockerfile

FROM node:20.11.1-alpine3.19

# Add our local certificate to the trusted store
# COPY src-root.crt /usr/local/share/ca-certificates/
COPY src-sub.crt /usr/local/share/ca-certificates/
COPY git-csm.example.com.crt /usr/local/share/ca-certificates/

# Update the trusted store (https://stackoverflow.com/a/67232164)
# RUN cat /usr/local/share/ca-certificates/src-root.crt >> /etc/ssl/certs/ca-certificates.crt  && \
RUN  cat /usr/local/share/ca-certificates/src-sub.crt >> /etc/ssl/certs/ca-certificates.crt && \
  cat /usr/local/share/ca-certificates/git-csm.example.com.crt >> /etc/ssl/certs/ca-certificates.crt && \
  apk --no-cache add curl git

# Setup node variables to respect the trusted store
ENV NODE_EXTRA_CA_CERTS=/usr/local/share/ca-certificates/git-csm.example.com.crt
ENV NODE_OPTIONS=--use-openssl-ca

Inside the image curl works normally (cert is correctly added to the local store)

curl https://git-csm.example.com
<html><body>You are being <a href="https://git-csm.example.com/users/sign_in">redirected</a>.</body></html>f5136286dd66:/#

But using the following code:

const axios = require('axios');
axios.get('https://git-csm.example.com')
    .then(response => {
        console.log('Status Code:', response.status);
        console.log('Body:', response.data);
    })
    .catch(error => {
        console.error('Error:', error);
    });

I ran into the error

Any ideas what am I doing wrong?
