Today when I try to send notification to https://exp.host/--/api/v2/push/send. But I receive the following error “Uncaught exception ‘ExponentPhpSDK\Exceptions\ExpoException’ with message 'There was an unknown error with the FCM server. See this error’s details for more information”.
Previously everytime I send push notification, it is working fine. It happens today only.
The PHP sdk is not maintained by us, but rather by the community. The best course of action I can recommend would be to create an issue here: https://github.com/Alymosul/exponent-server-sdk-php/issues and see if the maintainers can shed any light on what’s happening!
