`serializeRequest` performs `JSON.stringify` on a `Buffer`

function serializeRequest(config: ApifyRequestConfig): ApifyRequestConfig {

apify-client-js/src/interceptors.ts

Lines 49 to 50 in 5093b8f

	if (type === 'application/json' && typeof config.data === 'object') {
	config.data = stringifyWithFunctions(config.data);

apify-client-js/src/interceptors.ts

Lines 68 to 72 in 5093b8f

	function stringifyWithFunctions(obj: JsonObject) {
	return JSON.stringify(obj, (_key, value) => {
	return typeof value === 'function' ? value.toString() : value;
	});
	}

I was wondering why I was receiving {"type":"Buffer","data":[...]} instead of actual data...
This breaks .call(buffer, { contentType: 'application/json' }).

Passing a string does not work either because axios does this:
