Download Doc fails with API error

[christianst1984]

Description of the bug
When downloading all docs from timeline, it fails always around the same area.

To Reproduce
Steps to reproduce the behavior:

1. Go to /Users/Christian/Documents/TR/pdf
2. Ran the command pytr dl_docs ./
3. Wait for documents to load
4. See error

Expected behavior
All documents download, eventually (API-) failing documents are ignored and outputted to the end (e.g. for manual validation via app).

Additional context
Download works until reaching the same time area via e.g.
pytr dl_docs --last_days 65 ./

Do you know what kind of document it tries to download?

[christianst1984]

I assume* it's a "Gutschrift" (credit voucher) with a negative value (i.e. cost for me) on dividends.
It's not opening in the app, too, and I've now opened a support case with TR on this.

• narrowed this down to a date by playing with last_days parameter until it repeatedly fails, following by trying all documents manually in app where one fails as well.

Need to find out if it's possible to ignore a certain timeline ID so it does not try to fetch it via API.
(After the error pytr does not immediately terminate, but does not create add. output or downloads any files if it occurs.)

[marzzzello]

Yes, I need to implement some better error handling

[achisto]

I ran into the same problem and was also able to narrow it down to what I believe is the cause, just as with @christianst1984 I have one entry that doesn't open inside my app, although it's not a "Gutschrift" but an entry related to a merger of two companies.

Is there some way to tell the script to only download UNTIL a certain date? I really need to bulk download everything from 2020 but the only code I was able to find was something for the LAST days, for example pytr dl_docs --last_days 85 .

If there was another command that I don't yet know this could help "solve" the problem of the script's error handling for now.
