New Smart Contract Creation

[Bobur-kobilov]

hi, thank for opensourcing hemera project.
I have a few questions regarding smart contract creation.
** Reproduce **

1. Created Alice as operation
2. Invited Bob as user
3. When I want to create new smart contract, it is showing the following error "requires authorizers Bob,Alice, but only Alice were given. Details: N/A." I assigned Alice as operator and Bob as user.
   Any help would be appreciated

Hi @Bobur-kobilov, what you are seeing is the daml runtime preventing you (acting as Alice) from adding Bob into an obligable position (ie Alice forcing Bob into becoming a signatory). Given that you have added Bob as a user, Bob must have a hemera User contract. You must use the choices on this contract to initiate any workflow you desire (ie User_NewSmartContract or User_Transact etc). You can read more about DAML's authorization model here
