Thank you Michael,
Only if I try both options you suggested I get i both cases:
fatal: [ansible-test] => {'msg': "One or more undefined variables: 'dict'
object has no attribute 'mysqluserpass'", 'failed': True}
fatal: [ansible-test] => {'msg': "One or more undefined variables: 'dict'
object has no attribute 'mysqluserpass'", 'failed': True}
It looks like it does not pick up the variables defined in my
/etc/ansible/host_vars/ansible-test file.
