All Errors

This networking error occurs when Terraform cannot establish a connection to a cloud provider, registry, or remote resource. It typically indicates DNS resolution failures, network connectivity issues, or security group/firewall restrictions blocking the required ports.

Terraform state write failures occur when Terraform cannot persist state changes to your backend storage due to permission issues, backend misconfiguration, or serial number conflicts. This prevents infrastructure changes from being recorded and can leave your state in an inconsistent state.

The replace_triggered_by lifecycle argument is invalid because it references a variable, data source, or non-existent resource. This argument only accepts managed resource references and was introduced in Terraform 1.2.

Terraform cannot read a file due to incorrect path, missing file, or permission issues. This typically occurs when using the file() function or reading configuration files with relative paths that aren't resolved correctly.

Terraform's lifecycle meta-argument only accepts valid arguments like create_before_destroy, prevent_destroy, ignore_changes, precondition, and postcondition. This error occurs when you use an unsupported argument name or incorrect syntax in the lifecycle block.

The aws_lambda_function resource requires mutually exclusive code deployment options. You cannot use both filename and image_uri in the same Lambda function—choose one based on whether you're deploying from a local file, S3, or container image.

This error occurs when Terraform's SSH client cannot authenticate with a remote server during provisioner operations. It typically indicates missing or misconfigured authentication credentials (private key, password, or SSH agent).

This error occurs when Terraform's fileset() function receives a malformed glob pattern. Terraform glob patterns follow POSIX syntax, and certain pattern combinations are invalid or unsupported, causing the configuration parsing to fail.

Terraform Cloud requires that an organization be specified in your cloud block configuration. This error occurs when you haven't configured which Terraform Cloud organization your infrastructure belongs to.

The Terraform AWS provider throws a conflicting configuration error when both the deprecated cpu_core_count argument and the newer cpu_options block are present in the same aws_instance resource. This conflict occurs because these are two incompatible ways of specifying the same CPU configuration, with cpu_core_count being deprecated in favor of cpu_options.

This error occurs when you try to include a non-string value (like a list or tuple) directly in a string template using ${} interpolation syntax. Use the join() function or remove unnecessary interpolation syntax to fix it.

This Terraform error occurs when you provide an incompatible type (like a string, number, or object) where a list of strings is expected. Fix it by understanding Terraform's type system and using the correct list syntax in your configuration.

The duplicate resource error occurs when Terraform detects two or more resources with the same resource address (type and name combination) in your configuration. This prevents Terraform from planning or applying your infrastructure changes.

This error occurs when Terraform encounters a function name it doesn't recognize. Common causes include version mismatches, deprecated functions, or using Terragrunt functions in Terraform code.

This error occurs when using 'terraform import', 'terraform state rm', or 'terraform state mv' with a resource address that doesn't exist in your Terraform configuration files. Terraform requires the resource to be defined (or at least have a placeholder) in your .tf files before you can manage it via state commands.

The LimitExceededException error occurs when you exceed AWS KMS quotas during Terraform apply. This typically happens when creating too many KMS keys or hitting request rate limits in a region. AWS KMS has default limits like 100,000 customer-managed keys per region and rate limits for cryptographic operations.

The InvalidChangeBatch error occurs when Route53 rejects your Terraform resource record set changes due to conflicts, validation issues, or mismatched values. This guide covers the most common causes and solutions.

This error occurs when a version constraint string in your Terraform configuration uses incorrect syntax. Version constraints appear in required_version, required_providers blocks, and module version fields. Common causes include malformed operators, missing version numbers, empty strings, and unsupported syntax. The fix involves using proper version constraint operators and format.

The remote-exec provisioner failed to execute scripts on a remote resource. This typically occurs due to connectivity issues, authentication failures, or timeout problems when Terraform tries to run commands over SSH or WinRM.

This error occurs when Terraform tries to access an element (using bracket notation) of a value that is null. It happens with data sources that return no results or when accessing resources created conditionally with count.
