A notification received by a client provides the size of the property which if it is more than 1000 bytes doesn’t let the value into the notification.
The developer must handle the retrieval of the property.
There could be more than one reasons for that.
But as far as we use this package, we recognized some frequent issues:
The server address is not configured, you’re still using the default value who’s “localhost”.
Localhost is an interface for the “127.0.0.1” address, and not the real IPV4 device address.
To solve this, add : « Urls » : "http://[YourIPV4Address]:5000" under « AllowedHosts » : « * », line in appsettings.json file.
There is no native way to do that for now. The best you can do is hosting your server on an IIS server to connect with the machine name who’s never changing even if the network does.
Dig in it with the documentation.
