[Bug] ember not generating blueprints on z/OS

On z/OS, there seems to be an issue where ember generate does not generate the necessary files.

When running the test suite on z/OS:

  2) Acceptance: ember generate in-addon-dummy
       dummy blueprint foo:
     Error: ENOENT: no such file or directory, open '/home/jolai/zos_fork/ember-cli/tmp/20221011-6129-psrjd9.p2bb/my-addon/blueprints/foo/index.js'
      at Object.openSync (node:fs:609:3)
      at Object.readFileSync (node:fs:474:35)
      at FileHelper.get (node_modules/chai-files/src/file-helper.js:42:26)
      at Context.<anonymous> (tests/acceptance/addon-dummy-generate-test.js:58:43)

I have tried testing this feature with both the CLI and by calling it programmatically.

The blueprints are created successfully on Linux but on z/OS, nothing is created.

Linux

$ ember new my_test
$ cd my_test
$ ember generate blueprint foo --dummy
installing blueprint
      create blueprints/foo/index.js
$ ls blueprints/foo
index.js
$

z/OS

$ ember new my_test
$ cd my_test
$ ember generate blueprint foo --dummy
installing blueprint
$ ls blueprints/foo
ls: FSUM6785 File or directory "foo" is not found
$

Script.js

   const ember = require('../helpers/ember');
   let r2 = ember(['generate', 'blueprint', 'foo', '--dummy'])

Linux

$ node script.js
$ ls blueprints
foo

z/OS

$ node script.js
$ ls blueprints
ls: FSUM6785 File or directory "blueprints" is not found

Could someone point me to the code/components that generates the blueprint files?

Thanks
