X_train values are NaN in learning block although the features values are correct in the processing block

Question/Issue: X_train values are NaN in learning block although the features values are correct in the processing block.

**Project ID:**135755

Context/Use case: I have added a custom learning block which is a simple SVM for my project. The X_train values extracted from the X_train_split.npy are NaN, whereas the features extracted are correct and it is working fine in the processing block.

Also while running the command:

edge-impulse-blocks runner --download-data data/

I am unable to fetch data and it gives the error message:
[BLK] Selecting project with ID 135755
[BLK] Unable to retrieve learning block data No learning block found with ID 40
[BLK] Downloading files…
