Upgrade from v8.0.1 to v14.3.0 seems to have breaking changes: `backup` detects no remote folder; `stats` stays empty

[bentolor]

Hi there and again thank you very much for this awesome tool. Today i checked for potential updates and was astonished to realize the version jump from v8.0.1 to v14.3.0 available now. Awesome.

Nevertheless the upgrade breaks a few things and I'm not sure what breaking change I do miss from CHANGELOG.md. Sorry to bother but I'm running out of ideas:

v8.0.1

What do I miss? Configuration is unchanged in ~/.imap-backup/config.json?

For reference: This is my .imap-backup/config.json

{
  "accounts": [
    {
      "username": "my@email.com",
      "password": "#####REDACTED#############",
      "local_path": "/a/path",
      "folders": [
        {
          "name": "Archiv"
        },
        {
          "name": "Entwürfe"
        },
        {
          "name": "Gesendet"
        },
        {
          "name": "INBOX"

        }
      ],

    }
  ],

}

Hi @bentolor

Thanks for opening this issue. It's a bug with a recent change to the config file format, where the

[
{"name": "Archiv"}
...
]

part gets modified to be just

["ARCHIV", ...]

The quick fix for you would be to modify your config file, adding an indicator that it's in version 2.1 format:

  {
+ "version": "2.1",
    "accounts": [
      {
        "username": "my@email.com",

When the config file gets loaded, the change is made and a new version is set (2.2), but you'll only see that change written to disk if you make other modifications and save the file.

I've released version 14.4.0 to handle these cases.

Awesome @joeyates and many, many thanks! I was just about to adopt the suggested workaround when I got the Github notification. Just installed 14.4.0 and it works flawlessly.

Thank you very, very much!
