Arbitrary change of types

[AP2023]

Steps to reproduce

I have no idea. But I can describe the situation.
I have had a vault using Dataview for at least a year.

I defined a field as MultiFile and until last time, that is about 3 months ago, I could click and select multiple items as internal links. Today however doing so gives error “Type not expected, expected Text”.

I tried opening a new tab with an old file where it had multiple items and even there it gives that error, which it had never given.

I tried clicking on the field and it changed.

If that was not enough, doing Ctrl+Z went back to another tab and not the one with the focus!

Did you follow the troubleshooting guide?

Since this is an error that occurred on an old project, I can’t test it in the sandbox

Expected result

I want to be able to put multiple links in a Multifile field.

I expect the old files to continue to work

Actual result

Error “Type not expected, expected Text”.

I am sorry but I don’t understand this BR.

A quick summary for people who are trying to help you:

You have a list-type property whose values are links. But the property is showing the “Type mismatch” error / “Tipo non corretto”. And when you click on the property values, their format changes.

---

It makes me wonder if your YAML format wasn’t right for Obsidian.

For example, this format works in Obsidian:

---
esempio:
  - "[[a]]"
  - "[[b]]"
  - "[[c]]"
---

But this format gives a “Tipo non corretto” error.:

esempio: {'[[a]]', '[[b]]', '[[c]]'}

Does the first format above work in your vault?
Does your list property use that same format?

I don’t recall what the error was like in v1.8.10, and I don’t know what might have changed the format for you (maybe a plugin?, maybe an Obsidian update?), but checking the format might at least explain why you’re seeing the error.

I’m sorry if I failed to explain myself.

The format of my list is precisely that

esempio:
  - "[[path/a|]]"
  - "[[path/b]]"
  - "[[path/c]]"

I also verified on an old file, up to 3 months ago it worked, today opening it gave error, yet the format is the one that 3 months ago obsidian accepted and that you also confirmed to me to be correct.
I checked the updates. Obsidian seems to be installed. I’ve also done the plugin updates for that vault, I hadn’t thought of that, and even after reopening it still gives error

When you open the “All properties” list and right click on the property, is it a Text type? Because that would cause the “Type mismatch, expected Text” error:

If so, then when you change it to a List type, does that fix it?

@dawni

When you open the “All properties” list and right click on the property, is it a Text type

I tried the procedure and the error disappeared. But it puzzles me:

1 - why did it not give any problems until 3 months ago?

2 - why does this field appear correct from the class properties?

I’m pretty sure I’ve never opened that menu, so I don’t think I manually changed the property type before today

[dawni]

I don’t know what changed it. My first guesses from your plugins list are something in Auto Class, a script in Templater, or a field-type change via Metadata Menu. Or maybe something else.
