All Errors

This error occurs when Terraform encounters a resource type it doesn't recognize. Common causes include missing provider configuration, typos in resource type names, or using an unsupported resource type with the current provider version.

This error occurs when you assign a value to a Terraform variable or argument that expects a map(string) type, but you're providing a map with non-string values (numbers, booleans, lists, etc.). Terraform requires all values in a map(string) to be strings, and automatically converting incompatible types fails validation.

The "InvalidParameterValueException" error occurs when creating AWS Lambda functions with Terraform due to invalid configuration parameters. Common causes include S3 bucket region mismatches, VPC permission issues, IAM role problems, or exceeding service quotas.

This error occurs when passing an argument to a module that either doesn't exist as a variable definition or has an incorrect type. Fix it by ensuring the module has the required variable declared and you're passing the correct data type.

Terraform cannot find a referenced provider alias because it wasn't defined in your root module configuration. This error occurs when using aliased providers with modules without proper configuration passing.

A deposed object occurs when Terraform's "create_before_destroy" lifecycle fails mid-operation, leaving the old resource stuck in state. This happens when resource creation succeeds but destruction fails, or operations are interrupted. Fix by running terraform apply again or manually cleaning up state.

Terraform fails to import resources when the same import block ID is used multiple times. This error prevents Terraform from processing import configurations that reference different modules or resources with the same ID value.

The Expected attribute terminator error occurs when Terraform's HCL parser encounters invalid syntax in a resource or block attribute definition. This typically happens due to missing commas, incorrect quotation marks, or improper line breaks. Fix it by reviewing your configuration syntax carefully using terraform validate.

The "defaults" function was removed in Terraform 1.3.0 as part of the optional attributes feature stabilization. This error occurs when using the deprecated function with newer Terraform versions. Replace it with native default value syntax in variable type definitions.

The "Moved block with ambiguous destination" error occurs when multiple moved blocks in your Terraform configuration target the same destination resource. Terraform cannot determine which source should be moved to that destination, creating ambiguity that prevents the refactoring from proceeding.

The trimprefix function is unavailable in your Terraform version. This error occurs when using Terraform versions older than 0.12.16 that don't support the trimprefix built-in function for string manipulation.

This error occurs when applying a saved Terraform plan file that was created with different provider versions or configurations than your current setup. A plan file is environment-specific and cannot be reused after dependency changes. Resolve it by regenerating the plan and lock file in your current environment.

Since Terraform 0.13, only one required_providers block is allowed per module. This error occurs when your configuration has multiple required_providers blocks. Consolidate them into a single block to resolve this issue.

This error occurs when you try to access an attribute on a Terraform value that doesn't support attribute access, such as accessing properties on a list without indexing first. The fix depends on your data structure: use proper indexing for lists, conditional functions for optional resources, or verify attribute names match the resource schema.

This error occurs when Terraform encounters a syntax error where an argument value or block is expected but missing. Common causes include missing equals signs, incorrect block structure, or stray characters in your HCL configuration.

Terraform conditional expressions require both branches to return the same type. This error occurs when your ternary operator returns different types (e.g., string vs number), and Terraform's type system won't allow implicit conversion.

Terraform does not support nesting dynamic blocks directly inside other dynamic blocks. This limitation prevents you from using a dynamic block to generate nested dynamic blocks. You must use data structure flattening or other approaches to work around this constraint.

A saved Terraform plan can no longer be applied because the state was modified after the plan was created. Regenerating the plan resolves this issue.

Terraform cannot access the S3 backend state file due to insufficient AWS IAM permissions or misconfigured credentials. This prevents Terraform from reading or managing infrastructure state.

The 'Invalid multi-line string' error occurs when you attempt to split quoted strings across multiple lines in Terraform. Quoted strings must remain on a single line—use heredoc syntax or escape sequences for multi-line content.
