Templater Sudden Fail - Invalid reference date format

Help
1

I created this template for my weekly notes and started bulk creating them for this year. The template worked just fine for weeks 1-12 and then suddenly started giving me the “invalid reference date format” error on week 13 and on.

My weekly notes are formatted to be titled like: 2025-W02

# <% tp.date.weekday("[Week] WW - YYYY", 0, tp.file.title, "YYYY-[W]WW") %>
[[The Library|❖]] **• [[<% tp.date.weekday("YYYY-[W]WW", -7, tp.file.title, "YYYY-[W]WW") %>|«]] • [[<% tp.date.weekday("YYYY-[W]WW", 7, tp.file.title, "YYYY-[W]WW") %>|»]] • [[<%tp.date.weekday("YYYY-MM", 0, tp.file.title, "YYYY-[W]WW")%>|M<%tp.date.weekday("MM", 0, tp.file.title, "YYYY-[W]WW")%>]] • [[<%tp.date.now("YYYY-[Q]Q", 0, tp.file.title, "YYYY-MM-DD")%>|Q<%tp.date.now("Q", 0, tp.file.title, "YYYY-MM-DD")%>]] • [[<%tp.date.now("YYYY", 0, tp.file.title, "YYYY-MM-DD")%>|A<%tp.date.now("YYYY", 0, tp.file.title, "YYYY-MM-DD")%>]]**

Can anyone help me understand what's gone wrong? 

Thank you in advance!

In the Dataview query with the FROM line you’ve changed to tp.file.title,"YYYY-MM-DD". This is most likely the cause of your problem.

Ah, there were a few instances of those and correcting them did fix the issue! Thank you so much for pointing that out!
