在我的例子中，错误在这一行：
$attrs = Attribute::get();
$attribute_ids = $attrs->map->only(['id']); // solved
$attrs = Attribute::get();
$attribute_ids = $attrs->get(['id']); // here was my error
在我的情况下，代码中没有错误，然后重新启动本地服务器，但什么也没有发生 我清除了缓存、视图、重新运行服务器、composer转储自动加载，但什么都不应该起作用。 解决方案
$attrs = Attribute::get();
$attribute_ids = $attrs->get(['id']); // here was my error
"message": "array_key_exists(): The first argument should be either a string or an integer",
"exception": "ErrorException",
I terminate the current project server and run another project,
this project is run successfully, and after this I run my current project so it works like a charm.
