I am new to Eclipse ditto and my purpose is to connect esp8266 to ditto using mqtt.I am following this official post https://github.com/eclipse-ditto/ditto-examples/tree/9f6965f69f6f664ebfe3c24517f716682e91ca91/mqtt-bidirectional. I don’t know what is wrong with this, it gives error in first line starts with Curl, image link >> creating policy using

I tried without the first line and it worked. I am trying to understand the purpose of first line and how can I resolve this issue. Thanks
