API problems on the server side

Hi all,

I had a working client side API call to return some data - worked perfectly, but I want to conceal the source so implemented the same call on the server side, it’s an exact replica (and I’ve also tried all kinds of variations) but I keep getting the following error:

stack: "TypeError: data should be a string, Buffer or Uint8Array↵

Noting I can define the schema fine on the server side when using the URL and the query parameter that would be passed via the form - but when I try to use dynamic parameter value e.g. {{$_POST.profile}} then it fails.

Not sure if it’s a bug or if I’m just doing something wrong - has anyone experienced the above, and was able to solve it?
