Hi @Jean
- For compatibility between vRA 8.18.1 &vSphere 7 U3, they are compatible as shown below
Note:
- Since vRA 8.18.1 the compiling engine for both JS & python has been upgraded, so make sure first your code use latest one, as this may be the issue that make your vRO couldn't execute action / workflow. I have faced it after upgraded to that version 8.18.1; but didn't affect vRO from running.

Subject: Aria Automation 8.18.1 compatible with vCenter 7.X ?
Hello all,
I upgraded from Aria Automation 8.18 to 8.18.1 but I can no longer deploy or delete VMs in vCenter. I am on vCenter version 7u3
I debugged the problem
-If I disable my Subscriptions the VMs are created and deleted in the vCenter
the problem comes from the "Subscriptions" which are executed in vRO but which do not return control to it afterwards.
In vRA the Subscriptions fail in timeout
This is a new bug
Best regards
