I have tried with

sort.Strings(clientList)

now, and the same thing happens with the diff. As expected “http” is first on the sorted list, but the state is the opposite.

~ clientIdLists: [
          ~ [0]: "<http://sts.amazonaws.com|sts.amazonaws.com>" => "<https://github.com/re>"
          ~ [1]: "<https://github.com/re>" => "<http://sts.amazonaws.com|sts.amazonaws.com>"
        ]

Also manually assigning to indexes does not appear to work, unless I sort it manually by the order Pulumi returns it from the state the second time I run the stack.

Are there any general recommendations regarding this I have missed?

I just manually ordered them for now, since Sort did the opposite of the output from state. It’ll work for now.

ClientIdLists: pulumi.StringArray{
			pulumi.String(c.ClientIdLists[1]),
			pulumi.String(c.ClientIdLists[0]),
		},
