Generated CSR is not accepted by Compliance API

[faizytech-devsy]

`$data = CSRRequest::make()
->setUID($params['organization_identifier'])
->setSerialNumber('POS Name', 'G4', '18c46ddc-f8b6-4047-bab5-e3993471fd98')
->setCommonName($params['common_name'])
->setCountryName($params['country'])
->setOrganizationName($params['organization_name'])
->setOrganizationalUnitName($params['organization_unit_name'])
->setRegisteredAddress($params['location'])
->setInvoiceType(true, true) //invoice types , the default is true, true
->setCurrentZatcaEnv(CSRRequest::SANDBOX) //support all modes ['sandbox','simulation','core']
->setBusinessCategory($params['industry']);

    $CSR = GenerateCSR::fromRequest($data)->initialize()->generate();

    // writing the private_key to file
    openssl_pkey_export_to_file($CSR->getPrivateKey(), $storageDir.'/zatca_key.pem');`
    
    I have generate CSR from this code but the compliance API is not accepting it.
    
   CURL request below
    `curl --location 'https://gw-fatoora.zatca.gov.sa/e-invoicing/developer-portal/compliance' \

--header 'Accept-Version: V2'
--header 'OTP: 123345'
--header 'Accept: application/json'

--data '{
"csr": "MIIBBDCBrAIBADBNMQswCQYDVQQGEwJTQTEWMBQGA1UECwwNSmVkZGFoIEJyYW5jaDESMBAGA1UECgwJTXlDb21wYW55MRIwEAYDVQQDDAkxMjcuMC4wLjEwVjAQBgcqhkjOPQIBBgUrgQQACgNCAAQhByhJZ4MQsAPLjbSKTzZ9YNLUpPomdCFxrzVHxh3RmgAn5ndpUXvzDRwQFAMO0XLn0kQ7ZRjrjITRH6iDuyNuoAAwCgYIKoZIzj0EAwIDRwAwRAIgLLjoBYCmSeowe0x7ByDzmNUIwKDu25JCUqOeseRvcgYCIG/pIvidpdSDKy24naoSnfRsMOIWu6/YE041EU3YQcuC"
}'`

The output show Invalid Request with status 400.

@faizytech-devsy
converts Certificate Signing Request (CSR) into a Base64 encoded string than send to zatca.

@nomi-techie thanks for your help. I also discovered it just yesterday myself. I am amaze that this is not written anywhere in the documentation.
