Here is the error message from Heroku master push command
Git LFS: (0 of 5 files) 0 B / 167.50 MB
batch response: Repository or object not found: https://git.heroku.com/xxxx-brushlands-xx267.git/info/lfs/objects/batch
Check that it exists and that you have proper access to it
error: failed to push some refs to 'https://git.heroku.com/xxxx-brushlands-xx267.git'
Added a long text file to Git LFS (git for large files) and after that Heroku stopped working.
What might be the issue ?
