HTTP GET produces error

I am using the “HTTP Requests for Blueprints” plugin in UE5.1.1

When ever I trigger a simple HTTP GET, to any URL, it produces this error in the output log, following by the entire GET document:

Example, this is what it looks like fetching JSON file:

LogTemp: Error: HTTP
{
“student”: [

 { 
    "id":"01", 
    "name": "Tom", 
    "lastname": "Price" 
 }, 

 { 
    "id":"02", 
    "name": "Nick", 
    "lastname": "Thameson" 
 } 

]
}

Any ideas?
