Time series data import/visualization not working

**Describe the bug**
I m trying to label time series. But i have an error "Cannot read properties of undefined (reading 'length')"
It's seems it's currently impossible to visualise and label time series

**To Reproduce**
Steps to reproduce the behavior:
1. Launch label studio
docker run -it -p 8080:8080 -v $(pwd)/mydata:/label-studio/data heartexlabs/label-studio:latest
or
label-studio --username user --password user

2. Create new project. Import Time series data in csv. Select Time Series Template (anomaly/outliers/classification).
You can use the airPassenger.csv data from Kaggle.

3. Try to display/label the data.

**Expected behavior**
Be hable to see the time series and label it
