We are using async report api to generate the report and periodically fetch the status of the result, but when fetching the result, it said: "Report is pending, Wait until 201 response code" even in one day later after the report generation.

We use following restful api to request the report generation:
POST https://saap.jsreportonline.net/api/report
{
"template":
{
"engine": "handlebars",
"recipe": "phantom-pdf",
"content":"html template here",
"phantom": {
"margin": { "top": "0.45cm", "left": "0.5cm", "right": "0.5cm", "bottom": "0.9cm" },
"format" : "A4",
"header": "The header",
"footer": "The footer",
"headerHeight": "1.5cm",
"footerHeight": "1cm",
"resourceTimeout":90000
},
"data":
{},
"options": {
"timeout": 60000,
"reports": {
"save": true,
"async": true
}
}
}

**Once it had been done, it reported back a url to allow us fetch the report later (report id was modified): **
Async rendering in progress. Use Location response header to check the current status. Check it
<a href='https://saap.jsreportonline.net/reports/5b58ff0000000000000/status'>here</a>

But when we check that url in few hours even one day, it showed the following message asking us to wait endlessly:
Report is pending. Wait until 201 response status code

Could anyone please help? Thanks a lot!!

Michael
