this[#sentry].captureMessage is not a function

Hello I am using Ghost on Pikapods.

I ve not been posting on my blog for some months. today i posted a newsletter and i got the

”Uh-oh. Your post has been published but the email failed to send.

*this[#sentry].captureMessage is not a function

If the error persists, please verify your email settings.”*

Mailgun is set up, i also generated new API Key to be sure, but the issue persists.

Any suggestion?

there was an update and now is Unknown Error.
