When trying to create multiple issues from API, creation gets blocked after some operations. Getting below error when trying to process the API.

"message":"You have exceeded a secondary rate limit and have been temporarily blocked from content creation. Please retry your request again later."

At this time API header response, I am getting is below:

[NameValuePair(key=Server, value=GitHub.com), NameValuePair(key=Date, value=Mon, 05 Sep 2022 07:53:41 GMT), NameValuePair(key=Content-Type, value=application/json; charset=utf-8), NameValuePair(key=Transfer-Encoding, value=chunked), NameValuePair(key=X-OAuth-Scopes, value=admin:enterprise, admin:gpg_key, admin:org, admin:org_hook, admin:public_key, admin:repo_hook, delete:packages, delete_repo, repo, user, workflow, write:discussion, write:packages), NameValuePair(key=X-Accepted-OAuth-Scopes, value=), NameValuePair(key=X-GitHub-Media-Type, value=github.v3; format=json), NameValuePair(key=X-RateLimit-Limit, value=5000), NameValuePair(key=X-RateLimit-Remaining, value=4946), NameValuePair(key=X-RateLimit-Reset, value=1662367828), NameValuePair(key=X-RateLimit-Used, value=54), NameValuePair(key=X-RateLimit-Resource, value=core), NameValuePair(key=Access-Control-Expose-Headers, value=ETag, Link, Location, Retry-After, X-GitHub-OTP, X-RateLimit-Limit, X-RateLimit-Remaining, X-RateLimit-Used, X-RateLimit-Resource, X-RateLimit-Reset, X-OAuth-Scopes, X-Accepted-OAuth-Scopes, X-Poll-Interval, X-GitHub-Media-Type, X-GitHub-SSO, X-GitHub-Request-Id, Deprecation, Sunset), NameValuePair(key=Access-Control-Allow-Origin, value=*), NameValuePair(key=Strict-Transport-Security, value=max-age=31536000; includeSubdomains; preload), NameValuePair(key=X-Frame-Options, value=deny), NameValuePair(key=X-Content-Type-Options, value=nosniff), NameValuePair(key=X-XSS-Protection, value=0), NameValuePair(key=Referrer-Policy, value=origin-when-cross-origin, strict-origin-when-cross-origin), NameValuePair(key=Content-Security-Policy, value=default-src 'none'), NameValuePair(key=Vary, value=Accept-Encoding, Accept, X-Requested-With), NameValuePair(key=X-GitHub-Request-Id, value=77D2:7B0D:1C580A:203694:6315AB04)]

Here, we can see that X-RateLimit-Remaining's value=4946. So, the rate limit is remaining but still create operation is blocked.

What is the reason for this blocking? And is there a way from the header from which I can identify the failure cause? How I can differentiate this blocking from the normal rate limit exceeding blocking?
