Terraform CLI
Terraform found a block type that is not expected here
Error: Unsupported block type
Terraform found a nested block where the schema expected an argument assignment or a different configuration structure.
Error AtlasError Documentation and ResolutionObserved message
Error: Unsupported block type
Why it happens
- A nested block was used where Terraform expects an argument with an equals sign.
- Configuration was copied from a different provider version, syntax style, or Terraform generation.
- The block name is valid elsewhere but not in the current resource or module context.
How to fix it
- Check the schema for the resource or block and confirm whether the name should be an argument or a nested block.
- If Terraform suggests using an equals sign, rewrite the block as an argument assignment.
- Compare the configuration with current provider documentation rather than older examples.
