Error after upgrading to 5.70.0 `array_flip(): Can only flip string and integer values, entry skipped`

[danielfowler]

Bug description

I upgrade to 5.70.0 and I get this error wherever I have {{ get_content from="{ entry:id }" }} or {{ current_user:entries_fieldtype }}. My users are in Eloquent.

array_flip(): Can only flip string and integer values, entry skipped

How to reproduce

Upgrade to Statamic 5.70.0 and try using get_content in Antlers or an entries fieldtype within the user blueprint.

Here's my user.yaml blueprint:

    fields:
      -
        handle: studio_subscriptions
        field:
          type: entries
          width: 50
          collections:
            - studios

Here's my template:

      {{ current_user:studio_subscriptions scope="stud" }}
        ...
      {{ /current_user:studio_subscriptions }}

Another example, same/related issue using get_content

Here's my show.yaml collection blueprint:

        fields:
          -
            handle: cast_list
            field:
              type: grid
              display: 'Cast List'
              fields:
                -
                  handle: actor
                  field:
                    type: entries
                    max_items: 1
                    mode: tags
                    collections:
                      - performers
                    label: '{{ first_name }} {{ last_name }} ({{ email }})'
                    sort: 'last_name:asc|first_name:asc'
                    width: 50

Here's my template:

{{ cast_list }}
    {{ get_content:actor scope="act" }}
      ...
    {{ /get_content:actor }}
{{ /cast_list }}

Maybe there's better syntax for me to use, but this setup was working prior to 5.70.0. I rolled back to 5.67.0 and confirmed it went back to normal, then upgraded to 5.68 and 5.69 without issue. It blows up in 5.70.

Same here on php8.3

array_flip(): Can only flip string and integer values, entry skipped

{{ get_content:related_by_uri }} {{ partial:products/header }} <div class="container mx-auto px-4 py-12"> <div class="flex flex-row flex-wrap"> {{ cards }} {{ partial:products/clp-cards }} {{ /cards }} </div> </div> {{ /get_content:related_by_uri }}

After downgrading to 5.69, it's working again.

Same here after upgrading. I'm getting it when manually constructing a query builder and running count() on it.

[jasonvarga]

Would any of you be able to share your site? I can't reproduce this.

[daun]

This line is what's causing it on my end. It filters the query down to published entries. The null is probably in there because in some instances the published value is the default and thus not saved to yaml? Can't remember unfortunately but it was required to get it to work originally.

$query->whereIn('status', ['published', null]);

[danielfowler]

It appears to happen when get_content is called on a blank value. This is probably true for my current_user:studio_subscriptions too.

I reproduced it on a fresh install here: https://github.com/danielfowler/arrayFlip

On the home.antlers.html view, {{ get_content:actor }} fails because the first actor expected (within home.md) is not there.

[danielfowler]

Confirmed: if I add an arbitrary actor value, no error.
