filter by function includes for list properties

[iomadh]

Hi, The new Obsidian Properties functionality in 7.7.0 is brilliant, but I'm having trouble with one use case

It's not clear from the documentation where using includes is allowed with anything except the tags property, but it doesn't work, giving me an error

     filter by function task.file.property('project-state').includes('active')

    "TypeError: Cannot read properties of null (reading 'includes')"`

I can use

filter by function task.file.property('project-state') === 'active'

however when the property is of type list, the property can be rendered as

project-state:
  - active

and this doesn't match

So, is includes supported in list properties ?

Hi @iomadh, Apologies, this slipped through my net.

On re-reading it, I don't exactly understand what the question is. I can read it two different ways.

If you have solved your problem, could you add a note here saying what you did?

And if not, can you please say a bit more about what the problem is?

For example, is it:

• Only a problem when the property is a single value
• Only a problem when the property is a list
• Or is it a problem because you have a property which is sometimes a list and sometimes a single value?

I solved this by using

filter by function task.file.property('project-state') == 'active'

(note the one less equal's sign - I'm not a JS expert but think this is different to === )

but I also need to be careful only have a single value in the list (multiple values means that it doesn't match even if one of the values is a match)

Thank you for the update. 😄
