Hello,
https://trailhead.salesforce.com/modules/unlocked-packages-for-customers/units/build-your-first-unlocked-package
When i do this stage in the trailhead : on SFDX commande line programme, i am connected to my devhub and the command : sfdx force:package2:version:create --directory force-app --wait 10 to create the package version, which associates the metadata with the package.
i have this return :
ERROR :insufficient access rights on cross-reference id: 0HoB00000008Ohn.
