Invalid reaction on API

I’m trying to create a reaction on a post, but every time I get an error about the reaction being invalid.

I tried all the emoji_name like “:loading:”, “loading”.

I went to Postman to collect all the emoji from the post to check the syntax of writing emoji and in the end I would write it correctly.

But I just always get the same message by error: api.reaction.save_reaction.invalid.app_error

Could this be because I’m not explicitly specifying the user_id?

Hi, I ran into the same issue. Did you manage to find a solution?
