Hello,  I am running into an odd issue that I am activley troubleshooting as it will cause issues down the road if I want to change settings later. Basically for this issue all I am doing is creating a new ECS Task Definition which then is setup as a ScheduledTask using CloudWatch Rule and EventTargets.  On FIRST deploy everything works accordingly, upon modifying the task definition say just CPU it throws an error => “Preview Failed: unexpected unknown property Value”. I enabled DEBUG, but I am not sure what I am exactly looking for.

Hey James, what Pulumi CLI version are you on?

Running: 2.15.4, Pulumi.Aws is latest 3.*, with the latest plugin installed on my laptop of 3.21.0

Hello @chilly-hairdresser-56259, We are tracking this issue here

@chilly-hairdresser-56259 We’re actively investigating this issue. Did anything change for you dependencies-wise on this stack?

@faint-table-42725 I have not changed any package references. Mine currently are looking like this.

Thanks — that’s helpful. If you run with

PULUMI_DISABLE_PROVIDER_PREVIEW

does the update succeed?

@faint-table-42725 just saw your comment, testing now, will get back with you shortly

Thanks for confirming!
