Isse with sending push notifications from service

Hi,

We’re having some issues sending push notifications from a service. See attached screenshot. I believe this used to work previously, the first instance of this error I can find in our logs were June 3.

We are using a non-empty, runtime only, cardinality many user object class as input to the Push Notification action node.

Does anyone know what could be the issue here?

Hi! I have tried to look into this, and have some follow-up questions:

  • How many are in the recipient data source, i.e., how many users should receive the push notification?
  • Has this number grown over time, or specifically around June 3rd?
  • Does it fail every time?
