Hey @eric3,

Can you let me know the Webinar UUID for the webinar that you ran into this error on? This will help me to further investigate.

Thanks!

Hey @eric3,

Thanks for providing that ID, this was helpful for taking a closer look.

Have you run into this error since? I’m wondering if this could have been due to a race condition, if you were trying to register several users within a short period of time.

Thanks,  
Will

</div>

i agree with you, because i saw this response header:

> [@eric3](#):
>
> `X-RateLimit-Category: Light`

it should be rate error. but it haven’t return another rate error header, like : `X-RateLimit-Type` or `Retry-After` and response code should be 429, is it zoom side error?

Hey @eric3,

That’s correct, if you’re hitting your rate limit you should receive a 429 error. When you space your requests apart, are you still seeing this issue? Similarly, are you receiving any error messages for too many concurrent requests?:

Let me know—thanks!

seems not reproduce now,  
About `X-RateLimit-Category: Light` , i can found it on all of our zoom response. So, this header can’t help us find issue. there should be another issue.

Hey @eric3,

If you encounter this again and are able to reproduce, please let me know. In regards to the rate limit category, let me know if you have another question here.

Thanks,
