Dear @sudeep_stha7675

Thanks for reaching out, and welcome to our community.

You concern is not clear; can I kindly ask you to elaborate more and answer the below questions to ensure a comprehensive support as usual:
1- What is the environment that you create the CSR for?
2- what is the API that return Invalid Request?

Thanks,
Ibrahem Daoud.

default_bits = 2048
emailAddress = hada66dupport@hotmail.com
req_extensions = v3_req
x509_extensions = v3_ca
prompt = no
default_md = sha256
req_extensions = req_ext
distinguished_name = dn

[ dn ]

OU=RiyadhBranch
O=Jarir
CN=RIYADH …OR short address

[ v3_req ]
basicConstraints = CA:FALSE
keyUsage = digitalSignature, nonRepudiation, keyEncipherment

[req_ext]
