This is also happening to us both from the AWS AppSync console and in code. On occasion subscriptions will work and we can subscribe, but the majority of the time queryString and variables are empty and we are unable to validate requests.

We have no issues with Queries or Mutations running through Lambda Auth only subscriptions.

MichaelPHanley commented 2 months ago

After some troubleshooting, I'm nearly certain this results from AppSync sending the connection init message to the authorizer. This message doesn't contain the query or the variables. The start subscription message will include them. So if you do not allow the init to go through, neither will the variables or query.

This presents other problems with lambda auth caching in AppSync because the token is already authorized and cached without actually validating the values from the query.

Hi @wulianer, Thank you for bringing this up and conducting further analysis. As you mentioned, this issue needs to be addressed by the AppSync team. We will raise a ticket with them and keep this one updated with any progress.
