Hello! I am trying to build a demo app that reads data from S3 bucket. The steps are the following: Import AWSServices module (with dependencies, Encryption and Logging) Link AWSSernices AfterStartup microflow with the corresponding attribute in Project’s settings Add the Administration widget to the Home page When I try to set static credentials I receive “Region must not be null error”. As you can see on the picture (see attachments) I do specify the region. Studio Pro version is 9.4.0 UPD: Validation works fine if I set a default value for the RegionName attribute in Credentials entity. UPD: Added another picture to show that the entity attribute does not get set.
