#

you tried to access a slice with has 0 elements in it
without any line numbers it's hard to say
you should make sure the slice is at least length of 1 before accessing it

#

UserHash := userHashResponse.DisplayClaims.Xui[0].Uhs
guessing this line where Xui is a slice of 0

hasty dome
#

Yeah but why

#

It shouldn't be 0

silent owl
#

i see that's your question, sadly i do not have knowledge with xbl api to help on that

hasty dome
#

Am I dong it wrong with the struct or is it the api response?

#

{
"Properties": {
"SandboxId": "RETAIL",
"UserTokens": [
"TOKEN_HERE_FROM_PREVIOUS_STEP"
]
},
"RelyingParty": "rp://api.minecraftservices.com/",
"TokenType": "JWT"
}

#

that should be the userHashBody

#

Is it right?

#

@silent owl

#

{
"IssueInstant": "2021-02-07T21:41:03.6735105Z",
"NotAfter": "2021-02-08T13:41:03.6735105Z",
"Token": "SAVE_THIS_TOKEN",
"DisplayClaims": {
"xui": [
{
"uhs": "SAME_USER_HASH_AS_BEFORE"
}
]
}
}

#

that's the response

silent owl
#

you could try printing the raw premarshal json results responses

silent owl
hasty dome
#

No

#

that should be the response

#

i don't get that

#

@silent owl

silent owl
#

you dont need to tag me every response, i muted this server for pings anyways
i will be available on my own terms

silent owl
#

you havent shown what is the response you actually got

hasty dome
#

expected

#

let me print out the response

silent owl
#

yes that's what's necessary to understand who's wrong here

# 
    body, _ := io.ReadAll(resp.Body)

you are also silencing an error, errors useful for debugging might be lost in it

2022/10/04 22:06:59 Status Code: 400 Bad Request

#

nope

#

my request is bad

#

idrk what's wrong my request tho...

silent owl
#

you can also echo out the body and see if the json you sent is what you expected to be
