Flexible content registered as empty array on post creation

Hello,
I have a flexible content group attached to a post template. The problem I have is that on the publish action, when I create a new post, none of the blocks I added in the flexible content group saves.
On the update action tough, it saves just fine.

I’ve added a debug function attached to the wp native ‘save_post’ action, and the $_POST[‘acf’] is an empty array. This would explain why the ‘acf/save_post’ action isn’t triggered since it sees no change.

I think it’s worth mentioning that I use local JSON for the flexible content.

Technical details that might be useful:

– WordPress 5.8.2 Multisite
– ACF PRO 5.11.4 with local JSON.
– Environment setup on docker
– The theme is custom-made by us and it uses composer autoload psr-4.
– The platform does not use any other plugin.
– The JSON group is attached below.

Any idea what could trigger this behavior?

Thank you,
Andrei
