"SyntaxError: Unexpected token k in JSON at position 97" on version 7.0.36 / 7.0.37

[luzfcb]

This is a bug report.

What is the current behavior?

update heroku cli to any version between 7.0.36 and 7.0.37 (from apt-get or snap package)

try run heroku.

sudo DEBUG=* heroku update or sudo DEBUG=* heroku output:

fabio@luzfcb:~$ sudo DEBUG=* heroku update
  @oclif/config reading core plugin /usr/lib/heroku +0ms
  @oclif/config:heroku using manifest from /usr/lib/heroku/oclif.manifest.json +0ms

What is the expected behavior?

Run heroku cli normally, without any bugs

what it is in that file on your machine? I have {"version":"7.0.37","commands":{}} from apt-get.

@jdxcode my /usr/lib/heroku/oclif.manifest.json contains the same content

[luzfcb]

fabio@luzfcb:~$ sha1sum /usr/lib/heroku/oclif.manifest.json

is there any way to downgrade the debian or snap package? to me test all previous versions until I find one that works, and find out which version the bug was introduced.

[jdx]

try deleting ~/.local/share/heroku

[jdx]

you could try to downgrade, but this bug was almost certainly introduced in v7 which was a massive change so I don't think it would tell us anything

[luzfcb]

@jdxcode done. delete ~/.local/share/heroku/ fix the error.

I probably should have backed up the folder, to try to identify what the cause of the error was.

I remember that the only plugin I had installed was heroku-config, which was installed as follows

heroku plugins:install heroku-config 

I installed it again, and the error did not occur.

Thanks a lot for the help.

it seems if the ~/.local/share/heroku/package.json (where I store the plugin manifest) has a syntax error the CLI does not start. Strangely, this is wrapped in a try/catch that should just warn. I'll have to find out why it's erroring.
