Failed to persist entry: TypeError: Cannot read properties of undefined (reading 'includes')

I’m trying to post a blog entry via the Content Manager and I get: Failed to persist entry: TypeError: Cannot read properties of undefined (reading ‘includes’)

I’m unable to save my post! What should I do?

Sounds like you may have gotten logged out in the meantime, which can definitely happen depending on your configuration and how long you’ve had the page open vs when you logged in using Identity. I’d recommend copying your post content to another editor, reloading the editor, pasting the content back in and seeing if it works better :slight_smile:
