Tabular Model processing SQL Agent Job failure

I have set up a SQL Agent job to process my tabular model db, but I am getting the following non-descript error.

The tabular model processes fine processing it manually, but when I do it via SQL Agent job it fails almost instantly. We have done all the checks on credentials, logins, rights.

Any ideas/suggestions?
