The dynamic block's iterator argument is set to a complex expression (like a function call or attribute reference) instead of a simple variable name.

generic

动态块的 iterator 参数被设置为复杂表达式（如函数调用或属性引用），而不是简单的变量名。

95% success Use a simple, single-word identifier for the iterator that is not already in use in the current scope. For example, if iterating over a list of tags, use 'tag' as the iterator.

90% success If you have nested dynamic blocks, use distinct iterator names for each level, such as 'outer' and 'inner'.

```

使用一个简单的、单词的标识符作为迭代器，且该标识符在当前作用域中未被使用。例如，如果遍历标签列表，使用 'tag' 作为迭代器。

如果有嵌套的动态块，为每一层使用不同的迭代器名称，例如 'outer' 和 'inner'。

Common approaches that don't work:

90% fail
The iterator must be a new variable name, not an existing expression. Terraform uses it to create a temporary variable within the block.
60% fail
The default iterator 'each' works only if not already used by another dynamic block in the same resource. If 'each' is used elsewhere, it causes conflicts.
95% fail
The iterator must be an unquoted identifier, not a string. Quoting makes it a string literal, which is not a valid variable name.
