Hi @vstrelianyi can you post your Custom Field configuration? I'm wondering if you have the Select multiple values? option enabled.

[vstrelianyi]

Hi @ardiewen !
should I check for this option in ACF field configuration?

[vstrelianyi]

[vstrelianyi]

yes, you can select several options

[vstrelianyi]

btw I have found the same issue here in acf graphql plugin repo
wp-graphql/wp-graphql-acf#155

[ardiewen]

Yeah interesting... definitely related to the acf schema filter as mentioned in the other post. However the solve seems to be on this repo. I will see if I can test a potential fix.

[vstrelianyi]

That would be great! Thx a lot!

Hi @vstrelianyi, you'll need two PRs to fix the issue:

#568 on this repo
wp-graphql/wp-graphql-acf#297 on the acf plugin repo

Please note the following:

1. This will only be a temp fix due to significant breaking changes in wp-graphql-acf in v0.6.0

2. You MUST set a "Filter by Post Type" like you have in your screenshot. Failing to do so will cause the default type of your field to become PostObjectUnion which will cause conflicts with wp-graphql-woocommerce and consequently throw an error.

[vstrelianyi]

Ok. will try that!, thx!
so wp-graphql-acf v0.6.0 is on the way?

I think only https://github.com/wp-graphql/wp-graphql-acf/pull/297 on the acf plugin repo this edit is needed now thankfully.
