[starting from version: 2.8.17]
It is triggered when the Accelerator or the custom data source API server sends the 401 Unauthorized error in response to a Flexmonster's request. Only for "api" and "microsoft analysis services" data source types.
unauthorizederror can be used to automatically refresh authorization headers and resend the request in case of the 401 Unauthorized error:
flexmonster.on('unauthorizederror', function (callbackHandler) {
// other actions
// pass new request headers and resend the request
callbackHandler({
requestHeaders: {
AuthToken: "XXX"
}
});
});
