We've been using shopify admin API (REST) for over a year, but as of this month, we started getting
"Too Many Request" at random.
It looks different because the headers do not include the information documented here:
https://shopify.dev/docs/api/usage/rate-limits
We think this is a bug because:
1. When we get throttled, prior to the event the X-Shopify-Shop-Api-Call-Limit header does not show anything close to the limit.
2. There is no Retry-After header as proposed in the documentation.
3. We have a fibonacci backoff-retry that waits for 1 second, then 2 seconds, then 3 etc. 5 retries total and even after 20 seconds it still fails.
The headers are telling us this might be coming from CloudFlare.
Example:
data: {
errors: [
0: {
extensions: {1}
message: "You have sent too many requests. Try again soon."
}]}
headers: {
alt-svc: "h3=":443"; ma=86400, h3-29=":443"; ma=86400"

Has anybody experienced elevated error rates recently or other strange behavior?
