+          "errorType": "PermissionError",
+          "requestId": "<uuid:2>",

+          ]


@dfangl @joe4dev Seems like this test now expects a permissions error 🤔 Any pointers on how we should be configuring the user permissions when accessing the lambda FS? We currently set the following:

https://github.com/localstack/lambda-runtime-init/blob/9be92e099e99c9973f2e1730d1af6d4ffd769bb2/cmd/localstack/main.go#L155-L169

Can we parity-test/inspect this, or does the permission prohibit that?
If not, @dfangl might have a better guess. Maybe, try 600 🤷‍♂️

I think the tests makes no longer sense then - it was mean to introspect the environment of the init process, if that is no longer possible in AWS, there is no real point (although we could try to hide it in our containers as well, I don't necessarily see this as a priority)

Currently, only patch changes are allowed on main. Your PR labels (aws:lambda, semver: minor) indicate that it cannot be merged into the main at this time.
