Hi,
The error seems to be related to an external post type and the subscription plugin, mainly the lockers that are provided by this plugin. Lockers aren’t however active for the external posts – https://prnt.sc/rBCQaBb382dN so the option to set a locker doesn’t even appear in the post edit screen, but seems to resolve the problem – https://i.imgur.com/odOozKU.png
Thank you!
