Hello Brian Sullivan,
To publish the piplelines, The Data Factory Contributor role at the resource group level or above is needed
In publish context, Microsoft.DataFactory/factories/write permission applies.
So the user should have the "Contributor" role or a custom role with the "Microsoft.DataFactory/factories/write" permission needed.
and make sure user signed in to the correct Azure account.
if you are still facing the issue, please let me know.
