typeerror converting circular structure to json starting at constructor h code example

Example 1: UnhandledPromiseRejectionWarning: TypeError: Converting circular structure to JSON

I also ran into this issue. It was because I forgot to await for a promise.

Example 2: Converting circular structure to JSON

//The error means that the object you pass in the request has a circular reference, something like:

var a = {};
a.b = a;
