# sk184107 - Proxy API "set" commands return a "404 not found" message

## Symptoms

- * When using the Proxy API, `set` commands such as `set-static-route` fail and return a `404 Not Found message`.

* The response contains these errors:

  ```
  
   - "response-message" :
  
  { "code" : "err_validation_failed", "errors" : "address is required, mask-length is required, type is required", "message" : "Validation Error" }
  
   - { "code" : "err_gaia_api_send_command_failed", "message" : "Cannot send the command to the gateway: <Gateway ID< " }
  STATUS: 500
  ```

## Cause

When the Proxy API sent the request to the target Gateway, it removed necessary brackets from the raw data, causing the command validation to fail.

The log file `$FWDIR/log/api.elg` shows that the brackets were removed:
`payload = {'address': '1.2.3.0','mask-length': 24,'next-hop': 'add': `  
`'gateway':'<Gateway ID>','priority': 2,'type': 'gateway'}`
