I followed this deno tutorial to create a simple web server that interacts with firebase.
I created a copy of my deno project here.
If I make an api call to the endpoint to /user-requests, I get an error:
@firebase/firestore: Firestore (9.20.0): Could not reach Cloud Firestore backend. Backend didn't respond within 10 seconds.
This typically indicates that your device does not have a healthy Internet connection at the moment. The client will operate in offline mode until it is able to successfully connect to the backend.
I use these rules for Firestore database:
rules_version = '2';
service cloud.firestore {
match /databases/{database}/documents {
match /{document=**} {
allow read, write: if request.auth != null;
}
}
}
What is really strange I don't get this error for the copy of my deno project. I commented the rest of the code in my original deno project, but I am getting the error there.
How is it possible I am getting this error in one deno project, but I am not getting it in another deno project? Deno projects have the same source code and firebase projects configuration is the same.
Another question is why I am getting this error? I tried experimentalForceLongPolling option, experimentalAutoDetectLongPolling, and also this and nothing helped. Sometimes it's working, sometimes I am getting the error.
This is the output from debug-my.firebaseapp

edit:// seems like this issue is deno related, because I don't have this issue when I deployed my back-end in aws.
