A configuration file references a variable (var.*) that has not been declared with a variable block in any of the module's .tf files.

配置文件引用了变量（var.*），但该模块的任何 .tf 文件中都没有使用 variable 块声明该变量。

95% success Declare the missing variable in a .tf file (e.g., variables.tf) with an appropriate type and optional default.

在 .tf 文件（如 variables.tf）中声明缺失的变量，包含适当的类型和可选的默认值。

如果变量来自模块，确保正确引用模块的输出。使用 module.<module_name>.<output_name> 而不是 var.<name>。

如果不需要该变量，将引用替换为字面量或 local 值。

Common approaches that don't work:

95% fail
The .tfvars file only provides values; the variable must first be declared with a variable block in a .tf file.
80% fail
Changing the prefix doesn't create the variable. 'local' requires a locals block, which is a different construct.
90% fail
The issue is a missing variable declaration in the root module, not a missing module. Init doesn't add variable declarations.
