[bug] csi-external-snapshotter terraform error

[dejwsz]

Describe the bug

First fresh install goes OK, but later after another apply I have this:

│ Error: Invalid for_each argument
│
│   on .terraform/modules/eks_addons.eks-aws-addons/modules/aws/csi-external-snapshotter.tf line 38, in resource "kubectl_manifest" "csi-external-snapshotter":
│   38:   for_each  = local.csi-external-snapshotter.enabled ? { for v in local.csi-external-snapshotter_apply : lower(join("/", compact([v.data.apiVersion, v.data.kind, lookup(v.data.metadata, "namespace", ""), v.data.metadata.name]))) => v.content } : {}
│     ├────────────────
│     │ local.csi-external-snapshotter.enabled is true
│     │ local.csi-external-snapshotter_apply will be known only after apply
│
│ The "for_each" map includes keys derived from resource attributes that
│ cannot be determined until apply, and so Terraform cannot determine the
│ full set of keys that will identify the instances of this resource.
│
│ When working with unknown values in for_each, it's better to define the map
│ keys statically in your configuration and place apply-time results only in
│ the map values.
│
│ Alternatively, you could use the -target planning option to first apply
│ only the resources that the for_each value depends on, and then apply a
│ second time to fully converge.

What is the current behavior?

TF error after another apply with csi external snapshotter

How to reproduce? Please include a code sample if relevant.

Add cso external spanshotter - deploy it for a first time - it should be OK - and then do the next TF apply and the error should come up.

What's the expected behavior?

No TF error after consecutive TF apply commands

Was this as a first install ? Which version of TF/TG ?

[dejwsz]

At that time finally I used fixed version 6.1.0 of csi-external-snapshotter and I just used null_resource and kubectl to install it via yaml specs from the repo. Later I just injected fixed version as sidecar do EBS CSI controller. And it worked like that OK. I did not investigate csi-external-snapshotter.tf csi-external-snapshotter.tf due to lack of time then.
