I ran into this after upgrading ubuntu and SSL_CTX_use_certificate returning an error 1.
https://www.openssl.org/docs/man1.1.1/man3/SSL_CTX_get_security_level.html returns 2 on those systems, forbidding 1024 byte keys. The overall security of self-signed certificates is not great but this helper method is convenient :-)
