Hey @Frank01 , @ftballguy45 , and @fortuna-001
The docs for companyCreate do say that the mutation is only available on Plus stores, but the issue with the code above is that the CompanyCreateInput.
companyLocation.billingSameAsShipping field is set to true, which means the required Billing address is ignored and there is no Shipping address to add the necessary info:
I will flag this with our developers to request that a clearer error message gets raised if no address is provided.
All the best.
