Import fails with error about 'color' field

[vansens]

Hello,
I reinstalled my home server, not paying attention which version of paperless I was running previously.
Now whenever I try to run an import, I am getting the error below.

Please note I have been trying with the following versions already:

ng-0.9
ng-1.0.0
ng-1.1.0
ng-1.2.0
ng-1.2.1
ng-1.3.0
ng-1.3.1
ng-1.3.2
ng-1.4.0

Error:

Creating paperless_consumer_run ... done
Operations to perform:
Apply all migrations: admin, auth, contenttypes, documents, reminders, sessions
Running migrations:
No migrations to apply.
Traceback (most recent call last):

During handling of the above exception, another exception occurred:

The above exception was the direct cause of the following exception:

I did a little more looking around.
i think requiring to use the same paperless version you used when you did an export to perform a successful import is something that needs to be addressed. Back when I built the original server, I was using the latest tag for the docker image, so I really honestly do not know what version that was. Now I cannot import all the data, and I dumped about 20 hours work into that data already.

I will restart from scratch, but this time I will use a version number tag instead of "latest" so that I will be able to get back to that specific version later on.

Restore the data to the same version you used to create the backup, verify that it works, then upgrade.

"colour" got removed in 1.3.0 in favor of "color", which allows custom tag colors instead of a predefined palette of 16 colors. The importer indicates that this field does not exist anymore.
