When I use the --signcsr option op RHEL 9, my output is:

 + Requesting new certificate order from CA...
  + ERROR: An error occurred while sending post-request to https://acme-staging-v02.api.letsencrypt.org/acme/new-order (Status 400)

  "status": 400,
  "subproblems": [
    {
      "type": "urn:ietf:params:acme:error:malformed",
      "detail": "Invalid identifiers requested :: Domain name needs at least one dot",
      "status": 400,
      "identifier": {
        "type": "dns",
        "value": "certificate"
      }
    },

I traced it back to function "extract_altnames" where validation is done:

  if ! <<<"${csr}" "${OPENSSL}" req -verify -noout 2>/dev/null; then
    _exiterr "Certificate signing request isn't valid"
  fi

Manually running a verify on RHEL 8 (OpenSSL 1.1.1k FIPS 25 Mar 2021) is fine. No output whatsoever:

[dopheideb@client ~]$ openssl req -verify -noout <~/dehydrated/csr/some.csr 2>/dev/null
[dopheideb@client ~]$

Manually running a verify on RHEL 9 (OpenSSL 3.2.2 4 Jun 2024 (Library: OpenSSL 3.2.2 4 Jun 2024)) does output something:

[dopheideb@client bin]$ openssl req -verify -noout <~/dehydrated/csr/some.csr 2>/dev/null
Certificate request self-signature verify OK
[dopheideb@client bin]$

dehydrated does not anticipate output on stdout, which leads to the weird error message: the words "Certificate", "request", "self-signature", "verify", "OK" are treated as SAN parts, and that is obviously wrong.

The quickfix for me, was to simply redirect all output to /dev/null:

  if ! <<<"${csr}" "${OPENSSL}" req -verify -noout &>/dev/null; then
    _exiterr "Certificate signing request isn't valid"
  fi
