Missing Permissions and cannot create a custom role

[tradosappstore]

Hi,

I am trying to allow a user in my project to have sufficient permissions to be able to build custom models for AutoML.  I was able to give her the roles for AutoML Admin, API Keys Admin and Storage Admin, but she still gets this message:

Missing permissions: resourcemanager.projects.get serviceusage.services.get

I cannot see how to add these roles so I tried creating a custom role with all the prequisite permissions.  In doing this I could not use the Google console at all as the Add button is always greyed.  But I could add these two missing ones in a custom role using the shell commands.  However, I now can't add any of the AutoML stuff as this seems to create even more error messages and tells me this is just in testing.

I also can't add the custom role I created as it's only available to me under the Roles menu, but not as a role I can select against a principal.

I am sure I must be doing something really wrong here, or don't see why I don't have adequate permissions myself (I am the Owner).  Can anyone offer some advice here?

Thanks

Paul.
