Hi,

I'm having troubles doing a mass-config push. In my template I'm changing the hostname of a device. Afterwards I'm receiving a "INTERACTION_ERROR" and the push stops. A second push - after the hostname is set - is successfully..
May someone have any ideas how to fix that ?

thanks a lot
Christian

Hi Christian,

When Unimus interacts with devices, it typically learns part of the device prompt, usually the hostname, for more precise detection. If your device includes the hostname in its prompt and you change the hostname during an MCP, Unimus may fail to recognize it, resulting in an INTERACTION_ERROR.

You can resolve this by changing the prompt detection method in your MCP preset → Advanced settings → Prompt. Set it from Learning to Simple.

Hi Christian,

Unimus does not recognize the promptMatchingMode property. Specify it as promptMatchingModeEnum instead.

You can access the available v3 endpoints using the built-in Swagger UI at:
