Licensing: Ensure your license is either Community, Standard Trial, or higher. Some licenses only support creating and running agents within the Agent Builder. However, to deploy agents as processes and execute them, an appropriate license level is required. For detailed information, please refer to the UiPath licensing guide: Agents - Licensing.
(In my case I had basic trail license, so I had to upgarde to standard trial license)
Platform Units Allocation: Make sure to allocate Platform Units in Orchestrator by navigating to: Admin > Your Tenant > License > Edit Allocation.
Platform Units are necessary for AI-powered services, including agent execution, LLM calls, and more.
Process Configuration: While creating the agent process, ensure you configure:
The Integration Service connection and indexes for context (if applicable).
