Custom data not accessible in notification activities

[andrewmikhniuk]

Problem

When creating reactions or comments with createNotificationActivity: true and passing custom data via the custom parameter, this custom data is not accessible/propagated to the resulting notification activities.

How I'm adding reactions/comments with custom data:

Adding a reaction:

feedController.addActivityReaction(
  activityId: activityData.id,
  request: AddReactionRequest(
    type: 'like',
    createNotificationActivity: true,
    custom: {
      'communityId': 123,
      'communityName': 'My Community',
    },
  ),
);

Adding a comment:

activityController.addComment(
  request: ActivityAddCommentRequest(
    activityId: activityId,
    comment: 'Hello!',
    createNotificationActivity: true,
    custom: {
      'communityId': 123,
      'communityName': 'My Community',
    },
  ),
);

Expected Behavior

The custom data passed to AddReactionRequest or ActivityAddCommentRequest should be accessible somewhere in the notification ActivityData object - either via:

• activity.custom
• activity.notificationContext?.trigger?.custom
• activity.notificationContext?.reaction?.custom
• Or some other clearly documented property

Actual Behavior

The custom data appears to not be exposed anywhere in the notification activity. There's no clear way (or documented way) to retrieve the custom metadata that was passed when creating the reaction/comment.

Questions

1. Is the custom data supposed to be passed through to the notification activity?
2. If yes, where should I look for it in the ActivityData object?
3. If not, is this a feature request or a bug?

Hey @andrewmikhniuk, Thanks for reporting this! Custom data isn't currently being passed through to notification activities.

Right now, the custom data you pass when creating reactions or comments is only stored in the reaction/comment objects themselves. It's not being propagated to the notification activities that get created.

So you can access it when:

• Fetching the reaction or comment directly
• Getting activities (it's in latest_reactions)

But it's not available in the notification feed results, which is what you're seeing.

We're discussing this with the backend team to see if we can add this feature. I'll update here once we have more info on whether this will be implemented.
