Hi there!
Does anyone know why I got the following error when I try to communicate with the data store?
Context: I have a workflow with a single step to clean expired items in some data stores.
This workflow occasionally fails because of this error and it usually runs without errors.
I don’t know what causes this error:
Hello , on top of my mind right now, maybe it’s because there’re too many data store calls in a short period of time.
Could you try to delay a few hundreds milliseconds between each store.delete call to see if it improve?
Hello @U02SX7ETBFB, maybe you can provide some more insights for this case? 
Hello . Thanks for your reply.
Do you know where I could learn more about the data store’s limitations?
BTW, this error is prompted occasionally.
Hi Axel,
We are working on an update to pricing to help define limits on Data Stores and give more guidance on what the operational limits are.
If you’re receiving these errors, please consider either using less keys or storing less data inside of keys.
Hi Thanks for the info! I will consider your advice.
