Error: Request is throttled #99
Description
It doesn't happen all the time, however since I have imports of orders on cron job (every 3 minutes) I sometimes find my server crashed with this error:
{ Error: Request is throttled

Here is my setup:
if (!marketplaceCredentials.other.meta) {
marketplaceCredentials.other.meta = {
retry: true, // retry requests when throttled
next: true, // auto-paginate
limit: Infinity // only get this number of items (NOT the same as MaxRequestsPerPage)
}
}
this.mws = new MWSClient(marketplaceCredentials.other);
And here is where I am getting orders:
if (!query) {
return Promise.reject("Query not provided");
}
if (!query.fromDate) {
return Promise.reject("From date not provided");
}
return new Promise((resolve, reject) => {
this.mws.Orders.ListOrders({
MarketplaceId: this.credentials.other.marketplaceId,
LastUpdatedAfter: new Date(query.fromDate),
}).then(({result, metadata}) => {
let that = this;
console.log("getOrders => orders.length", result.length);
return Promise.map(result, function (orderItem, index) {
return that.mws.Orders.ListOrderItems({AmazonOrderId: orderItem.AmazonOrderId}).then(res => {
console.log("orderItem.AmazonOrderId", orderItem.AmazonOrderId);
orderItem.listOrderItems = res.result;
return Promise.resolve(orderItem);
});
}, {concurrency: 5});
}).then(function (result) {
resolve(result);
}).catch(error => {
console.log(error);
reject(error);
});
});
