.exceptions.UnhandledRPCError: Execution error: missing required active authority: Missing Active Authority

Good afternoon! I am developing operations for my version of the blockchain based on Bitshares-Core. I decided to switch to a new version of Python-Bitshares. After calling the "create_asset" method (or trying to send the "Asset_create" operation), an execution error "Execution error: missing required active authority: Missing Active Authority" constantly occurs. I imported the keys into my wallet. For example, the "transfer" operation works correctly. The operations are successfully performed via the cli_wallet API (I send requests via NodeRPC), but there are problems with the witness API.. What could be the problem?

Compare the create_asset and Asset_create calls with the transfer operation, focusing on the imported wallet keys and the difference between the cli_wallet API via NodeRPC and the witness API. Reproduce the missing active authority error and determine what authority or request detail is absent; done means the cause is documented or asset creation works through the intended API.
