Facebook Marketing API (#2654) Account Request Limits Reached, Sub Error Code:1870024 - facebook

Question

We've been using Facebook Marketing API v4.0. For an account, I keep getting error below. We cannot find any info about this sub error on Facebook docs. Our client deleted some Custom Audiences in their account but nothing changed.
{"error":
{"message":"(#2654) Account Request Limits Reached: You've reached the total number of times
you can create a Custom Audience through one or more ad accounts in this business.",
"type":"OAuthException",
"code":2654,
"error_subcode":1870024,
"fbtrace_id":"AmN2PwJB8utcYZCXu2y-9TF"}
}

You can check in the Changelog of the v4.0 API under Breaking Changes
- Ads Management here:
Updated the the rate limit for several areas under Marketing API. This includes:
custom_audience - Per each ad account in a one-hour time period:
Standard Tier Apps: Minimum of 190000 + 40 * Number of Active custom audiences. Maximum of 700000.
Dev Tier Apps: Minimum of 5000 + 40 * Number of Active custom audiences. Maximum of 700000.
You can also check the Business Use Case Rate Limits in the header of the response X-Business-Use-Case-Usage as described here, like:
x-business-use-case-usage: {
"{business-object-id}": [
{
"type": "{rate-limit-type}", //Type of BUC rate limit logic being applied.
"call_count": 100, //Percentage of calls made.
"total_cputime": 25, //Percentage of the total CPU time that has been used.
"total_time": 25, //Percentage of the total time that has been used.
"estimated_time_to_regain_access": 19 //Time in minutes to regain access.
}
],

{
"type": "ads_management",
"call_count": 95,
"total_cputime": 20,
"total_time": 20,
"estimated_time_to_regain_access": 0
}
],

"call_count": 97,

...
}
Hope this help
