Hello,
Last night I’ve noticed that my account appears to be “bugged” when it comes to group calls and this is happening to all Roblox games (even ones I don’t even own) that uses the :IsInGroup & :GetRankInGroup functions.
Every time, this error appears:
Nothing in code was changed so confused as to why its giving the “Invalid info for group” error. Group Id is correct
Is this from a game you made or is it someone elses game?
The script might be at fault here
this is from a game I made, but no the script is right and has not been changed.
but any other game utilizing these functions doesn’t work for me as well
Hmm… You should re-tag this post to bugs. This is clearly something freaky in Roblox’s database or the way :GetRankInGroup() is handled.
I am also having this issue, and have filed a bug report here:
This is a roblox bug they have somehow concocted when changing stuff without checking like usual.
As a workaround for now you could try using the web apis. I’ve attached some sample functions on how to use them below.
local HttpService = game.HttpService
local function isInGroup(userid, groupid)
local data = {}
xpcall(function(...)
data = HttpService:JSONDecode(HttpService:GetAsync(string.format("https://groups.roproxy.com/v2/users/%s/groups/roles", userid))).data
end, warn)
for _, group in data do
if group.group.id == groupid then return true end
end
return false
end
local function getRankInGroup(userid, groupid)
local data = {}
xpcall(function(...)
data = HttpService:JSONDecode(HttpService:GetAsync(string.format("https://groups.roproxy.com/v2/users/%s/groups/roles", userid))).data
end, warn)
for _, group in data do
if group.group.id == groupid then return group.role.rank end
end
return 0
end
To get around the HttpService not being able to make requests to roblox.com, I’m using RoProxy, but you can use a different proxy if you like.
Finally, someone else with this issue. Hope this gets fixed soon ^ _ ^
Can i ask how you get Roproxy to work exactly???
As you can see from the functions I’ve provided above, you simply replace roblox.com with roproxy.com.
Odd… I dont remember api being like this-
“i am a great developer” when i cant even use the API correctly 
It’s not you, it’s Roblox’s backend developers.
Did they change it??? Because the one i tried was from the Wiki and a post that listed them.
