I am able to post successfully using the Facebook node without receiving any errors. The post is correctly published on the page with privacy set to everyone and I (the page administrator) can see it on the page.
But, If I visit my page from another FB account I can’t see the post. Also if I share that post in a group I can see it, but the other group users see the error “This Content Isn’t Available Right Now”.
What am I doing wrong?
I have an update:
If I view the post using Business Suite, I click on the edit menu, and then I click on save, now the post is viewable by everyone and I can share it with others without any problem.
The Facebook Graph API node would be a simple wrapper around Meta’s Graph API. So the visibility would be determined by the endpoint behaviour and your account settings.
Perhaps you might want to reach out to a community focused on Facebook rather than n8n with this one? I reckon you have a better chance on finding the right settings this way.
