quick fix:

utils.py

1116    for expression in date_formats(day_first):
1117        try:
1118            upload_date = datetime.datetime.strptime(date_str, expression).strftime('%Y%m%d')
1119        except ValueError:
1120            pass
1121        except:     # added case for generic exception
1122            pass

Post the full output of youtube-dl when run with -v, i.e. add -v flag to your command line, copy the whole output and post it in the issue body wrapped in ``` for better formatting. It should look similar to this:

$ youtube-dl -v <your command line>

Do not post screenshots of verbose log only plain text is acceptable.

The output (including the first lines) contains important debugging information. Issues without the full output are often not reproducible and therefore do not get solved in short order, if ever.

It only appens in python script inside a Kodi addon... if you care I can post the full Kodi log and code excerpt

[dstftw]

I don't care about Kodi logs. You must post youtube-dl log. You pass 'verbose': True in params dict to YoutubeDL in order to enable verbosity programmatically.

here is the log with verbose enabled:

Possibly related to this python bug.

[anohren]

It would be great if this could be considered for a workaround.

I'm consistently running into this when using the SendToKodi plugin that suffers from it.

It didn't seem like it would be fixed in python any time soon, the last time I looked at that python bug link.

[laurentbacall]

I concur with @anohren
It'd be great to have a workaround for this python issue affecting youtube-dl for more than two years, as the python team won't budge.
