The number of requests made per second is too high and has exceeded
the allowable limit. The recommended approach to handle this error
is to wait about 5 seconds and then retry the request. Note that
this does not guarantee the request will succeed. If it fails
again, try increasing the wait time.
Another way to mitigate this error is to limit requests to 8 per
second for Ad Manager 360 accounts, or 2 per second for Ad Manager
accounts. Once again this does not guarantee that every request
will succeed, but may help reduce the number of times you receive
this error.
UNKNOWN
The value returned if the actual value is not exposed by the requested API version.
REPORT_JOB_LIMIT
This user has exceeded the allowed number of new report requests
per hour (this includes both reports run via the UI and reports run
via ReportService.runReportJob). The recommended approach to handle this error
is to wait about 10 minutes and then retry the request. Note that
this does not guarantee the request will succeed. If it fails
again, try increasing the wait time.
Another way to mitigate this error is to limit the number of new
report requests to 250 per hour per user. Once again, this does not
guarantee that every request will succeed, but may help reduce the
number of times you receive this error.
SEGMENT_POPULATION_LIMIT
This network has exceeded the allowed number of identifiers uploaded within a 24 hour period.
The recommended approach to handle this error is to wait 30 minutes and then retry the
request. Note that this does not guarantee the request will succeed. If it fails again, try
increasing the wait time.
