Hi @jmatiasmastro , I already found what was causing the error Error 412: Account id not found to fetch user profile, and it was basically due to the lack of selection of the feed that I wanted to display in the shortcodes, and I had no feed selected.

Essentially, I just needed to select the account there, which is why the connection error occurred.
