I'm doing an HTTP request using fetch to an old API which I cannot modify. I'm getting the error below:

TypeError: fetch failed
    at Object.fetch (node:internal/deps/undici/undici:11576:11)
    at process.processTicksAndRejections (node:internal/process/task_queues:95:5) {
  cause: [Error: C0A7AF98167F0000:error:0A000152:SSL routines:final_renegotiate:unsafe legacy renegotiation disabled:../deps/openssl/openssl/ssl/statem/extensions.c:922:
  ] {
    library: 'SSL routines',
    reason: 'unsafe legacy renegotiation disabled',
    code: 'ERR_SSL_UNSAFE_LEGACY_RENEGOTIATION_DISABLED'
  }
}

How can I enable unsafe legacy renegotiation? (fetch is called from an API route)
