According doc https://rocket.chat/docs/developer-guides/rest-api/users/setavatar
I'm trying to call (/api/v1/users.setAvatar) to set user avatar but I get this error :
{
"success": false,
"error": "Match error: Unknown key in field username"
}
when I change username to userId and test It works but with username it's not working.

Please show an example command of how you are able to reproduce this.

This is working fine for me on 0.57.1

curl -H "X-Auth-Token: mytoken" -H "X-User-Id: myuserid" \
-F "image=@hubot.jpg" https://myserver/api/v1/users.setAvatar

How do you set the "username"?

[graywolf336]

@localguru you even tried setting the avatar to another user by providing their username?

[localguru]

@graywolf336 no, I only tested to change my own avatar. How do I pass the "username" via curl?

If I try - as admin - to change another user's avatar by "userid" I get an error:

{
  "status": "error",
  "message": "You must be logged in to do this."
}

Shouldn't that be possible as admin? But through the webinterface there is also no way for changing avatars of other users as admin.

[graywolf336]

What command was you using to do it? As it is possible, we developed it and tested it a while back.

[localguru]

Same as above just with the userid of another user

curl -H "X-Auth-Token: my-admin-user-token" -H "X-User-Id: another-user-id" \
-F "image=@hubot.jpg" https://myserver/api/v1/users.setAvatar

[graywolf336]

That's why then, that is the incorrect usage. Check the documentation: https://rocket.chat/docs/developer-guides/rest-api/users/setavatar

[localguru]

Sorry, don't understand. Could you post an example please.

[graywolf336]

You always have to use your own user id when calling it. However, some api endpoints allow passing in a userId: 'id' or username: 'uusernamehere' in the body of the call. That is what I'm talking about

Hi all.

I can confirm that in current version 0.57.2 api request users.setAvatar not working if you use username parameter in payload of request.

Example:

curl -H "X-Auth-Token: adminauthtoken" \
     -H "X-User-Id: adminuserid" \
     -H "Content-type:application/json" \
     -d '{"username": "username", "avatarUrl": "http://domain.tld/link/to/avatars/user_avatar.jpg"}' \
     http://my_rocketchat_instance/api/v1/users.setAvatar

Result:

{
  "success": false,
  "error": "Match error: Unknown key in field username"
}

Ok, let's try userId instead:

curl -H "X-Auth-Token: adminauthtoken" \
     -H "X-User-Id: adminuserid" \
     -H "Content-type:application/json" \
     -d '{"userId": "userIdhere", "avatarUrl": "http://domain.tld/link/to/avatars/user_avatar.jpg"}' \
     http://my_rocketchat_instance/api/v1/users.setAvatar

Result:

{
  "success": true
}

Good. Now let's look at source:
line 189 of users.js

i don't see here anything about username parameter.

Please correct me if i am wrong.
