Meaning

Same causes as unsupported arguments. With AWS provider 4+, many S3 settings (versioning, lifecycle, logging, acl) became separate resources (aws_s3_bucket_versioning). Check whether it should be an argument (attr = {}) instead of a block, and block nesting.

Common causes

  • Block removed/renamed in newer provider
  • Should be an attribute object not a block
  • Wrong nesting level
  • Typo
  • Dynamic block syntax needed

⚡ Quick fix

  1. Use the new resource/nested block per provider docs
  2. Convert block {} to attr = {} (or reverse)
  3. Pin the provider version you wrote the code for

Detailed fix by platform

Terraform

  1. resource "aws_s3_bucket_versioning" "v" { bucket = aws_s3_bucket.b.id versioning_configuration { status = "Enabled" } }

How to diagnose

  1. Block — In schema?
  2. Provider — Version split?
  3. Syntax — Block vs attribute?
