Unable to load kibana dash board

Hi I am getting the below error while loading the kibana dashboard could someone please help me resolve this.

Loading index pattern filebeat-:
{"_index":".kibana_7.13.3_001","_type":"index-pattern","_id":"filebeat-
","found":false}curl: (3) Host name ' ' contains bad letter
./load.sh: line 121: -d: command not found

Hi, it appears the error originates from your curl command rather than anything Kibana related. What exactly are your trying to do?
