This appears to be due to a change in the algorithm used for determining the toString of an Object. See step 16 of 19.1.3.6 Object.prototype.toString ( )
const form = new FormData();
assert(form.toString() == "[object FormData]", "toString() results in [object FormData]")
assert(Object.prototype.toString.call(form) == "[object FormData]", "Object.prototype.toString.call(form) results in [object FormData]")
In version 2.3.2 of FormData, the second assertion will fail as Object.prototype.toString.call(form) returns [object Object]
The fix for this is to add support for the toStringTag symbol, like the following:
if (Symbol && Symbol.toStringTag) {
Object.defineProperty(FormData.prototype, Symbol.toStringTag, {
value: 'FormData',
writable: false,
enumerable: false,
configurable: true
});
}
