Hello im deploying a brand new package to our existing packaging org and am hitting a tone of errors, im following the instructions (https://developer.salesforce.com/docs/atlas.en-us.packagingGuide.meta/packagingGuide/sfdx_dev_build_man_pack_deploy.htm) but the project is failing due to 'object does not exist' or 'varible does not exist' but all these are part of the meta im trying to deploy... 

im running the command :

sfdx force:mdapi:deploy --deploydir "my deploydir"  --targetusername me@example.com

The only thing i can think of is that this package has a new namespace, can a packaging org only handle one namespace/ do i need seperate orgs (i have a devhub for the namespace).
