While trying to use the API to duplicate a Task i receive the following message.
“You have made too many requests recently. Please, be chill”.
I need to clarify though , that this message comes as a response only when i try to use the Duplicate EndPoint , whenever i try anything else (Eg. get / create a Task , a Project , etc) i can do it without any issues. According to the API specification i should get a Job Repsonse which i can track but i never got anything else except the above message.
You get that message when you reach 1500 calls within 1 minute for a premium account, or 150 for a free account. Just wait a little and try again.
This is a premium account and my issue is certainly not related to quota , since at the same time i am getting this error all other API requests succeed without any issues. As explained above , this is only happening on the “duplicate” end point.
I think it is a little bit more complicated than that, and the “cost” of the request is actually computed. So 1 call to duplicate might result in a thousand objects being touched. See “Cost limits” on Asana
That being said, you can’t really “paginate” your duplication… 
That effectively means that we can not use the API to duplicate not even a single Task due to the “Costs Limits” , cause i am getting this response while , simply , trying the CURL example found inside the Duplicate Docs , but using a valid to our Corporation Task ID. (Note : I have a few hundreds that i have to duplicate and doing it by hand is not an option.)
Even if the “Cost Limit” is the culprit , there is an actual issue with its implementation. The reason is that the Tasks at hand , have a few custom text fields (not more than 30 characters each) , a single note (not more than 100 characters) and are only manually connected with one simple Project to inherit those Custom Fields. So if a Task like that is reaching the “Costs Limit” something is not working as expected according to the " The vast majority of developers will be unaffected by the cost limit" found in the docs. In my eyes this is a very simple “query” and not something that should be treated specially.
Nevertheless , i have already accomplished my task with a Work Around. I wrote a Deep-Copy class and with the help of a few endpoints that work fine (GetTasks , GetTask , CreateTask , search , etc) i was able to create a custom duplication procedure. But i would certainly prefer using the Duplicate EndPoint in the future than my Custom implementation.
