Предполагаю, что ошибка в неправильно объявленном типе но как указать правильно. Вот куски кода где возникает ошибки

SBuf
Ssl::AsnToSBuf(const ASN1_STRING &buffer)
{
    return SBuf(reinterpret_cast<const char *>(buffer.data), buffer.length);
}

/// OpenSSL ASN1_STRING_to_UTF8() wrapper
static std::optional<SBuf>
ParseAsUtf8(const ASN1_STRING &asnBuffer)
{
    unsigned char *utfBuffer = nullptr;
    const auto conversionResult = ASN1_STRING_to_UTF8(&utfBuffer, &asnBuffer);
    if (conversionResult < 0) {
        debugs(83, 3, "failed" << Ssl::ReportAndForgetErrors);
        return std::nullopt;
    }
    Assure(utfBuffer);
    const auto utfChars = reinterpret_cast<char *>(utfBuffer);
    const auto utfLength = static_cast<size_t>(conversionResult);
    Ssl::UniqueCString bufferDestroyer(utfChars);
    return SBuf(utfChars, utfLength);
}

и вот
