How do I resolve the ‘don’t impersonate other users’ (900) / 403 error?

This article shows you how to take care of this Stream Feeds error:

`The policy "Don't impersonate other users" (900) blocked this request, please consult the documentation https://getstream.io/docs/,

This error is associated with the actor field when you are adding an activity. You can either actually remove the field or add a prefix. The two options are shown below.

1. Do not include the actor in the activity

const activityfeed = {
    'verb': 'add',
   'object': 'picture:10',
   'time': new Date()
};

const addactivity = await testFeed.addActivity(activityfeed);

2. Mention the actor with the prefix "SU:"

const activityfeed = {
   'actor': "SU:"+ userID,
   'verb': 'add',
   'object': 'picture:10',
   'time': new Date()
};

const addactivity = await testFeed.addActivity(activityfeed);
