Provider produced invalid plan / inconsistent final plan Terraform Origin: Platform & cloud OSI layer 7 · Application Last updated 5 Nov 2026

Terraform: Error: Provider produced invalid plan — provider produced an invalid plan for aws_x.y, but we are tolerating it because it is using the legacy plugin SDK

The provider changed planned values between plan and apply (a provider bug), so Terraform aborts.

Meaning

Update the provider, avoid computed/unknown values changing between plan and apply (e.g. timestamp() or uuid() in arguments), and consider saved plan staleness. For "inconsistent final plan", values unknown at plan time resolved differently at apply — re-plan and apply again; replace non-deterministic expressions.

Common causes

  • Non-deterministic expressions (timestamp(), uuid()) in resource arguments
  • Provider bug
  • Unknown values resolved differently at apply
  • Modules using depends_on producing unknowns
  • Changes made between plan and apply

⚡ Quick fix

  1. terraform init -upgrade; re-plan and apply
  2. Remove timestamp()/random from arguments (use lifecycle { ignore_changes } or time_static)
  3. Report/check the provider issue tracker

Detailed fix by platform

Terraform

  1. terraform plan -out=tfplan && terraform apply tfplan

How to diagnose

  1. Expression — Non-deterministic?
  2. Provider — Updated?
  3. Plan — Fresh?
