Welcome to our community!

Please don't post pictures of text, logs or code. They are difficult to read, impossible to search and replicate (if it's code), and some people may not be even able to see them

So, I am trying to reindex the elasticsearch indices with the below request, and I am using Dev tools in Kibana for this operation.
"""
POST _reindex
{
"source": {
"index": "flows-2023.02.25-000314"
},
"dest": {
"index": "dev_index_new"
}
}
"""
and it produced the output as below
"""
{
"error" : {
"root_cause" : [
{
"type" : "parse_exception",
"reason" : "request body is required"
}
],
"type" : "parse_exception",
"reason" : "request body is required"
},
"status" : 400
}
"""
