[FCM] notification that includes double quotes is not received

Plugins
#1

I found a nasty bug which made me debug my workflows for a couple of hours. Sending message via FCM plugin with text that includes double quotes fails. When message body is:

  1. test - notification is displayed
  2. 'test' - notification is displayed
  3. "test" - notification is NOT displayed

I sent "test" from FCM console and notification is displayed so seems like a problem with the plugin

Hey @aart.st ,

Thanks for reaching out! :pray:

Oof, I feel your pain—debugging for hours is never fun! :sweat_smile:

Thanks for sharing the details about the issue with the FCM plugin. From what I can tell, the issue is likely happening because the plugin isn’t escaping double quotes properly in the message body. Double quotes are special characters in JSON (which FCM uses for its API), and if they’re not escaped, it can mess up the API call and cause the notification to fail. The FCM console probably handles this for you by escaping the quotes automatically, but the plugin doesn’t seem to be doing the same.

Here’s a quick workaround you can try: before sending the message through the plugin, escape the double quotes by replacing every " with ". In Bubble, you can do this with the “Replace all” function. For example:

  • Store your message in a variable, like “message_body”.
  • Use “Replace all” to change every " to ", and save it as something like “escaped_message_body”.
  • Then, send “escaped_message_body” through the FCM plugin.

So if your message is “test”, it’ll become “test”, which should format correctly for FCM and show up as a notification.

I’d also suggest using Bubble’s debugger to double-check what’s being sent—make sure the escaped version is going through properly. Also, I found some threads on Bubble’s forums about similar issues with APIs and quotation marks, like this one, which might give you some extra context.

Give this a shot and let me know how it goes! If it’s still not working, we can dig deeper—maybe there’s a setting in the plugin we’re missing, or it might need an update. Happy to help either way! :blush:
