• scaleway_object_bucket

Terraform Configuration Files

resource "scaleway_object_bucket" "this" {
  id                  = "fr-par/nexus-cloud-proxies"

    prefix  = "snapshots/"
    tags    = {
      "deleted" = "true"
    }
    expiration {
      days = 1
    }
  }
}

Debug Output

Panic Output

Expected Behavior

The bucket with the desired lifecycle rule should be created or if the bucket exists (my case) the lifecycle rule should be created.

Actual Behavior

I have the error:
Error: error putting Object Storage lifecycle: MalformedXML: Only one field is accepeted in Filter, either Prefix, Tag or And status code: 400, request id: txg6aff11ceeac94af797db-XXXXXXXXXXXX, host id: txg6aff11ceeac94af797db-XXXXXXXXXXXX

Steps to Reproduce

1. terraform apply

Important Factoids

I took a look in the code and the issue comes from the code in https://github.com/scaleway/terraform-provider-scaleway/blob/master/scaleway/resource_object_bucket.go#L353 lines 353-368:

		tags := expandObjectBucketTags(r["tags"])
		filter := &s3.LifecycleRuleFilter{}
		if len(tags) == 1 {
			filter.SetTag(tags[0])
		}
		if len(tags) > 1 {
			lifecycleRuleAndOp := &s3.LifecycleRuleAndOperator{}
			if len(r["prefix"].(string)) > 0 {
				lifecycleRuleAndOp.SetPrefix(r["prefix"].(string))
			}
			lifecycleRuleAndOp.SetTags(tags)
			filter.SetAnd(lifecycleRuleAndOp)
		} else if len(r["prefix"].(string)) > 0 {
			filter.SetPrefix(r["prefix"].(string))
		}
		rule.SetFilter(filter)

In fact, if I add two or more tags in the lifecycle rule there is no error.
Basically, if I have the following lifecycle declaration:

  lifecycle_rule {
    enabled = true
    id      = "Expire-soft-deleted-objects-in-blobstore-s3-snapshots"
    prefix  = "snapshots/"
    tags    = {
      "deleted" = "true"
    }
    expiration {
      days = 1
    }
  }

The second condition in the code above (if len(tags) > 1 ) is not true and the LifecycleRuleAndOperator is not used what causes the issue.

So, we have the following scenarios:
len(tags) >= 0 && len(prefix) == 0 --> Works
len(tags) == 0 && len(prefix) >= 1 --> Works
len(tags) > 1 && len(prefix) >= 1 --> Works
len(tags) == 1 && len(prefix) >= 1 --> Fails

References

This problem is related to the use of the LifecycleRuleAndOperator
