For customers on some older plans a max queries per second (QPS) is set. This may lead to the error message you're seeing.
Customers on current plans (as of 2023) have unlimited QPS.
Check max QPS
If you're seeing the error above, your application has a maximum number of queries per second (QPS). By restricting the max QPS we ensure fast response times for every customer.
The max QPS for your application depends on the plan you are on.
You can check your max QPS from the dashboard. Go to the dashboard -> API monitoring:
Then click 'Performance' and scroll down to the 'Maximum queries per second' chart:
The above show that this application has 20 QPS included in its plan.
Here is more information in our documentation.
You can upgrade to a newer plan to get unlimited queries per second.
