unable to create a subdirectory as a file was created before by script itself

Hi, here is the end of the log :

unpkg.com/[email protected]
Error: ENOTDIR: not a directory, mkdir '/home/fabien/Prototypes/har-offline/unpkg.com/[email protected]/dist'
    at Object.mkdirSync (node:fs:1400:3)

  syscall: 'mkdir',
  code: 'ENOTDIR',
  path: '/home/fabien/Prototypes/har-offline/unpkg.com/[email protected]/dist'
}

Files and directories until that point were created properly. If I check

fabien@fabien-CORSAIR-ONE-i160:~/Prototypes/har-offline$ ls unpkg.com/[email protected] -l
-rw-rw-r-- 1 fabien fabien 107488 apr  2 09:50 unpkg.com/[email protected]

seems to be a file, not a directory. Maybe it's due to redirections.
