Can not add reaction with API

Troubleshooting
3

Hello,

I am using the following:

  • URL: /api/v4/reactions
  • Method: POST
  • JSON: {“user_id”:MY_ID,“post_id”:POST_ID,“emoji_name”:":email:",“created_at”:1590137025.2786}

I am not sure about created_at field, I used microtime() PHP function to generate it. I also tried 0, as described in the API.

The error I am geting is: api.reaction.save_reaction.user_id.app_error
