I tried to use the Froxlor API with curl but I got stuck at "Invalid request header". This is the curl command I am trying: curl --location --request POST 'https://MYDOMAIN/api.php' \ --header 'secret: mysecretstring' \ --header 'apikey: myapikey' \ --header 'Content-Type: application/json' \ --data-raw '{ "command": "Froxlor.listFunctions" }' of course I insert the real domain and secret strings this is clear not the issue. If I understand the code right it fails even befor
