EXPORT. OVERLEAF Invalid format of field 'urldate'
I have been using my Zotero bibliography in Overleaf for quite some time with no problems what so ever.
Until I started getting several messages of error like this one in Overleaf:
./main.bbl:
Package biblatex Warning: Biber reported the following issues
(biblatex) with 'appelgren_data_2014':
(biblatex) - Invalid format of field 'urldate'.
I have no idea how to fix it. I've tried to change the 'date' reference for some of the references directly on Zotero (from 'mdy' to 'y'). It seems to have worked, but it is a lot of trouble to do that with all the references. Besides, I don't want to lose this kind of information from Zotero.
Advices?

- If using bibtex, go to "My LIbrary" here on the page, select the item in question, click on the "Export" (folder with green arrow) button at the top right, select bibtex as format and see if the TZ is in that export
- If using biblatex, do the same thing, but instead of clicking, copy the link. It will look something like this: https://www.zotero.org/api/users/2433/items/top?limit=25&format=bibtex&key=[someRandomLetters]&v=1
Change bibtex to biblatex and paste the link into your browser and see what that output looks like. (make sure to not post your key, the part that I have substituted with [someRandomLetters] here)
(but just to repeat, we also haven't seen a single example of this in Zotero; this has only ever appeared in Overleaf's Zotero integration)
@dstillman this appears to be a regression in v3 of the API:
https://api.zotero.org/groups/684844/items/65R5MEPB?format=bibtex&v=1 is fine but
https://api.zotero.org/groups/684844/items/65R5MEPB?format=bibtex&v=3
(or just https://api.zotero.org/groups/684844/items/65R5MEPB?format=bibtex , which is equivalent of course)
produces urldate = {2019-02-18TZ},
