Assignment not getting evaluated

Hi,

My saved coding assignment is not getting evaluated. Getting this below error:

The code segment:

def train_val_split(time, series, time_step=SPLIT_TIME):
# [code removed - moderator]

I tried refreshing the workspace using instructions from here. But that didnt change anything.

Would appreciate further help here.

Thanks

Please check notebook metadata

Thanks. The metadata indeed looks corrupted (attached screenshot below).

I followed the steps to refresh the workspace again. But the metadata remains the same.

Will report to Coursera based on the instructions
