I have a script where I look up a record in a table through the API. It worked couple of days ago but now i constantly get 500 Internal server error

let ninoxProductUpdate := do as server
http("POST", "https://api.ninoxdb.de/v1/teams/" + team + "/databases/" + TestDatabase + "/tables/A/records", {

'Content-Type': "application/json"
}, {

F: stockCount,
G: stockLimit,
J: comments,
K: isOnSale,
L: costPrice,
M: isHidden,
R: weight,
Q: dropShipping,
