Google app engine this application does not exist error

Question

I use java backend on google's appengine with eclipse sdk. When I tried to update my backend with eclipse, i got error that says

com.google.appengine.tools.admin.HttpIoException: Error posting to URL: >https://appengine.google.com/api/appversion/create?app_id=infra-filament-610&version=2& 409 Conflict Another transaction by user heodong91 is already in progress for app: s~infra-filament-610, version: 2. >That user can undo the transaction with "appcfg rollback".

So I ran the rollback on terminal with command

appcfg.sh rollback /Users/Donghyeok/PlanItBackend/src/main/webapp

but its giving me this error

Unable to rollback app: Error posting to URL: httpsds://appengine.google.com/api/appversion/rollback?>app_id=infra-filament-610&version=2& 404 Not Found This application does not exist (app_id=u'infra-filament-610').

So then I looked up possible solutions and ran this on the command line.

appcfg.sh --no_cookies rollback /Users/Donghyeok/PlanItBackend/src/main/webapp

It still gave me the same error

This is try #3 Unable to rollback app: Error posting to URL: https://appengine.google.com/api/appversion/rollback?app_id=infra-filament-610&version=2& 404 Not Found This application does not exist (app_id=u'infra-filament-610').

I tried again with --oauth2 option and still give me the same error.

I also tried removing .appcfg_oauth2_tokens_java file but same error.

I have tried many things in many combinations but I wasn't able to solve this issue. So the main problem is the first one. But to solve this I had to rollback, but its not letting me rollback. Could someone please help? I'm like desperate...

This can be fixed by changing the app name in app.yaml to the name of the project (visible in Google Developer Console, often suffixed with a number). It may also work by simply adding at the end of your rollback command line the following:

--application=<projectname>
