question

I am trying to add currency to users using cloudscript and I'm getting this result:

{"Result":null,"CustomData":null,"Error":{"HttpCode":400,"HttpStatus":"BadRequest","Error":1000,"ErrorMessage":"Invalid input parameters","ErrorDetails":{"PlayFabId":["must be a hex-encoded number"]},"RequestId":"Failed to Enumerate RequestId. Exception message: Enumeration has not started. Call MoveNext.","RetryAfterSeconds":null}}

It appears that the problem is that the PlayFabId "must be a hex-encoded number", however I am passing the same PlayFabId string that successfully works on an earlier "PlayFabAdminAPI.GetUserAccountInfoAsync" call, so it should have been identical.

One of these is "6CD7FFC2F611745D" and is the Master Player account, it doesn't have anything in there that would make it an invalid hex string. I have even attempted to append "0x" at the start to see if that affects it, but this makes no difference to the error response.

Parameters passed to Cloudscript:

{"currency":"CC","count":8,"classid":"CE0A7FC0D41F163A","mid":"F0891069681D6C27,43D9831D3094A7C6,7856B6CF0F7E7B73,6CD7FFC2F611745D,8A849383AE9D5DFA"}

^ the "mid" string will be comma separated into an array in the cloud script.

Cloud Script Function (Azure):
