Good morning,  
Read-to-runtime action nodes with “object.property has no value” filters are failing after the last upgrade in our staging environment. We’re not having this issue in production environment, but dev, test and staging are all having this issue.

Hi Petter!

We have disabled Flows (seems like the error is related) in Create. Can you try again in Development (maybe do a minor change first to force deploy) and see if the error still occurs?

Related error:

Condition “Has all of” used on a multicardinality runtime property gives this error if there is at least 1 element in the property. When it’s empty, the condition works as expected.
