Deleting folder throws an error

[LucaBlackDragon]

Bug Description
When deleting folders, the library throws a FTPError No such file or directory.
This issue might be caused by the initial / present in folder entries, but not in file entries, as far as I can tell from error logs:

...  
📄 Delete: _next/static/chunks/main-4008b7bc3b992c03.js  ← no initial / here    
📁 Delete: _next/data/37sYNwt2oKohzL5dgd1TZ              ← no initial / here too
...
removing "_next/static/chunks/main-4008b7bc3b992c03.js"   ← still no initial /, this works
removing folder "/_next/data/37sYNwt2oKohzL5dgd1TZ"       ← a / has appeared, and this throws

FTPError: 550 /_next/data/37sYNwt2oKohzL5dgd1TZ: No such file or directory

I have also opened a linked issue on SamKirkland/FTP-Deploy-Action.

I have found the line that introduces the initial /:

ftp-deploy/src/syncProvider.ts

Line 127 in 9039859

const absoluteFolderPath = "/" + (this.serverPath.startsWith("./") ? this.serverPath.replace("./", "") : this.serverPath) + folderPath;

There is no such logic in the removeFile() function, so I don't know why it is necessary here.
@SamKirkland can you help us?

[LucaBlackDragon]

Or maybe the "No such file or directory" error itself is misleading and can be ignored, as done in the removeFile() function:

ftp-deploy/src/syncProvider.ts

Line 113 in 9039859

if (e.code === ErrorCode.FileNotFoundOrNoAccess) {

Fixing this may actually fix the following errors :

• FTPError: 550 ~partytown: No such file or directory FTP-Deploy-Action#422
• 550 assets: No such file or directory FTP-Deploy-Action#312
• 550 .ftp-deploy-sync-state.json: No such file or directory FTP-Deploy-Action#324

[LucaBlackDragon]

The thing is the original code's purpose is not so clear, so I don't know if one could just copy the logic from removeFile() or if something different is needed.
@SamKirkland can you tell us more?

So, for those who still have the problem, I've added the following code to my ci.yml file and it worked

- name: 🏗️ Build
  run: npm run build:fooBar && mkdir -p dist/apps/fooBar/path/to/troublesome/folder

I'm basically creating the not existing file/folder so that it can delete it.
I know, it's stupid, but how well.

Finally find out the solution to this error.
I decided to post it on stackoverflow

TL;DR
Delete the .ftp-deploy-sync-state.json file found on the server
