In SharePoint Online you should avoid the creation of master pages...if you create a master page for a SPO site and you apply it, you are going to disconnect that sites from many innovations being added by Microsoft...Migh I ask why are you creating a custom master page for SPO?

@Juan Carlos González Martín Yea I have created a custom master page, even if I applied default master page oslo and seattle error remain same
