After creating Integration Profile, "Download Subscriptions" job might fail with the following error:
Error: ScopedGlideDateTime(java.lang.String) ScopedGlideDateTime(com.glide.glideobject.GlideDateTime) (sys_script_include.452dbe4087f233000088ed4d87cb0b4d.script; line 68)
The reason is that "external_created" might be returned by third party with null value. The script include that thrown the error (SaasAction) should have handled this exception better.
This problem is currently under review. You can contact ServiceNow Technical Support or subscribe to this Known Error article by clicking the Subscribe button at the top right of this article to be notified when more information becomes available.
Until then, you can import attached update on SaasAction script include to handle this null value exception.
