ValeError: time data 'date_submitted' does not match format '%Y-%m-%d'

Hi,
I used the downloaded data from GISAID but when I run I get the following error:
File “/Users/Winnie/opt/miniconda3/envs/nextstrain/lib/python3.8/_strptime.py”, line 349, in _strptime
raise ValueError(“time data %r does not match format %r” %
ValueError: time data ‘date_submitted’ does not match format ‘%Y-%m-%d’
ERROR: All samples have been dropped! Check filter rules and metadata file format.

Hi @winnie97 – could you clarify which “downloaded data” you are using? Also which build you are trying to run & which step is causing the error? I’ll try to track down where this is being introduced.
