I have created a Conversational Agent and deployed it in the orchestrator. However, whenever I try to run it, I get an error.
{“Code”:“Agent.Unknown”,“Title”:“Using Conversational Engine, but FpsProperties is not provided”,“Detail”:“Using Conversational Engine, but FpsProperties is not provided\n”,“Category”:null,“Status”:500}
Please help me with this. @UiPath_Community
Run it in agent , not in orchestrator. Go to cloud.UiPath > 9 dot > agent > Conversational agent.
Now you able to chat with your conversational agent.
Documentation for reference - Agents - Conversational agents
Please mark as solution , Thanks

You’re getting this error because the conversational engine in UiPath require fpsproperties for this you can check your agent.json
It should contain something like this inside the engine section:
{
“engine”: {
“type”: “Conversational”,
“fpsProperties”: {
“language”: “en”,
“modality”: “text”
}
}
}
If fpsProperties is missing, you need to add it manually in the agent.json before packaging & deploying again.
Has anyone validated this works? Having issues. I would like to expose the conversational agent through MCP and have an external User Interface call it.
However, the above issue is blocking me
UiPath MCP expects the Conversational Agent to have valid fpsProperties before it can be exposed as an API endpoint. Without this block, the runtime doesn’t know what language/modality to use, so it fails.
Cheers
It didn’t seem to like the Agent.JSON with the Engine Properties, I’ll retry it and report back
This is the structure for agent.json
{
“engine”: {
“type”: “Conversational”,
“fpsProperties”: {
“language”: “en”,
“modality”: “text”
}
}
}
Ensure this block is correctly included before packaging and deployment.
hey all, the conversational agent isn’t meant to be used as a tool. We’ll look into supporting that later down the line, but we only support direct 1:1 chats with a conversational agent at this time.
Within Autopilot for Everyone, please don’t “Enable in Autopilot” as this will enumerate the conversational agent as a tool in A4E and it will fail.
To access a conversational agent in A4E (starting with version 25.8.1), all you need to do is select the conversational agent from the dropdown at the top of A4E (the same dropdown in which you select a specialized Autopilot).
