addExistingSourceFiles error

Describe the bug
Version: 14.4.1

When adding source files through project.addExistingSourceFiles(["*.ts", "bar/*.ts"]);, I get the following error -

C:\dev\git\scratch\test_ts-simple-ast\node_modules\ts-simple-ast\dist\Project.js:168
            finally { if (e_2) throw e_2.error; }
                               ^

Error: ENOTDIR: not a directory, scandir 'C:\dev\git\scratch\test_ts-simple-ast\bar\chec.ts'

It works fine when I do project.addExistingSourceFiles(["foo/*.ts", "bar/*.ts"]);, or just project.addExistingSourceFiles(["*.ts"]);

To Reproduce

Set up a dir structure as

foobar.ts
foo/
      bar.ts
bar/
     foo.ts

And then run project.addExistingSourceFiles(["*.ts", "bar/*.ts"]);,

Expected behavior

Should be able to add the specified files in the specified glob pattern.

Thanks for reporting @sajal50! I had internally named a method incorrectly then used it according to its incorrect name (classic). Fixed and released in 14.4.2.
