1.2.2.1 broke potato annotation tasks

[christianschuler8989]

Halli und Hallo and Greetings,
I am a big fan of Potato, thank you for creating it! :)
Sadly, I just noticed that something inside of potato must have broken recently.

Reproduction
( This error happens either way, whether I install potato-annotation via pip, or clone the repository. )

• I run the command to start the annotation task
• potato start summarization_evaluation/
• The server starts and I can navigate to it via the web browser (Firefox)
• I can create a new account as usual
• The moment I try to log into the annotation task, the browser displays a message along the lines of: "an internal server error has occurred"

Error Description / Terminal Output

potato start summarization_evaluation/
starting server from summarization_evaluation/configs/summ-eval.yaml
the current working directory is: /home/username/directory_to_project/summarization_evaluation/

KeyError: 'label_suggestions'

Workaround
For the time being, installing a previous version solves this problem:

pip uninstall potato-annotation

pip install potato-annotation==1.2.2.0

Probable Cause
Something in the newest commit [1.2.2.1 supports displaying label suggestions]
