Hi @Mohammad_Rahmani - couple things:
- multi-tenancy requires Identity; multi-tenancy is a feature that is enabled by the full Camunda stack, not a feature that is fully enabled by Zeebe alone
- have you enabled multi-tenancy in all the other services? Just setting
ZEEBE_GATEWAY_MULTITENANCY_ENABLED
isn’t enough. Refer to the documentation here; because you are using Docker, this thread may be helpful also. - even though you specified the default tenant ID, I believe you also need to go into Identity and configure that tenant
(Also, just in case: the free license is only for non-production use of Operate and Tasklist.)
