This article provides details about an issue where the config_cmd API fails to generate configuration and returns the error: {"details": "unknown"}.

During the issue, Mist is unable to push the configuration to the SRX device. The config_cmd API fails to generate the configuration and returns the following error: {"details": "unknown"}.

This issue can occur due to a configuration error, such as using the same name for a WAN link and a LAN network. MIST relies on these names to create zones, and having identical names causes a conflict, preventing MIST from generating the configuration.

Ensure that the WAN link name and the LAN network name are unique. Using different names will avoid conflicts and allow MIST to generate the configuration successfully.
