I’m experiencing an issue with the Firebase Console where the Cloud Messaging section is stuck on loading. After inspecting the developer console, I found that an API call to the Identity Toolkit API is returning a 404 error.

Error Message:

json

{
“error”: {
“code”: 404,
“message”: “Requested entity was not found.”,
“status”: “NOT_FOUND”
}
}

API Endpoint Returning Error:

• Verified that the required APIs (Identity Toolkit API, Firebase Authentication API, and Firebase Cloud Messaging API) are enabled in the Google Cloud Console.
• Checked API key permissions to ensure they are correctly configured.
• Cleared browser cache and cookies, and tried accessing the Firebase Console in incognito mode.
• Tried different browsers and networks to rule out browser or network-specific issues.
• Verified that service accounts have the necessary permissions.
• Consulted the Firebase Status Dashboard to ensure no ongoing outages.
