Hello SOTI team,

I am developing an app with SOTI-SNAP wherein I use javascript to use a AspNetCore REST service from our server located on the internet.
When developing I use the preview function of SOTI-Snap in the browser (Chrome). Calls with the GET method works from preview. But the POST method returns the following error in the browser console:

Access to XMLHttpRequest at 'https://[OurServer].com/soticlean/TimeRecords' from origin 'https://s3.eu-central-1.amazonaws.com' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: It does not have HTTP ok status.

Here my Javascript call from my app:

var settings = {
"url": Snap.variables.getValue("gvarServiceURL"),
"method": "POST",
"timeout": 0,
"headers": {
"Content-Type": "application/json"
},
"data": JSON.stringify(
{
"deviceUid": data.deviceUid,
"date": data.date
}),
};

return $.ajax(settings).done(function (response) {
console.log(JSON.stringify(response));
alert(JSON.stringify(response));

}).fail(function (response) {
alert(JSON.stringify(response));
});
}

And here the customHeader section from my Web.config of my AspNetCore REST Service:

...

<system.webServer>
<httpProtocol>
<customHeaders>
<add name="Access-Control-Allow-Origin" value="https://s3.eu-central-1.amazonaws.com" />
<add name="Access-Control-Allow-Headers" value="Content-Type"/>
<add name="Access-Control-Allow-Methods" value="GET,PUT,POST,DELETE,OPTIONS" />
</customHeaders>
</httpProtocol>

....

I hope someone can help me.

Thanks a lot

Martin
