Amazon Login: Refresh Token triggering Internal Server Error

I'm testing an Alexa Voice Service integration. Quick question about "refresh_token" requests, where you trade a refresh token for an access token [https://developer.amazon.com/public/apis/engage/login-with-amazon/docs/authorization_code_grant.html]

These were working for me a while back, but then have recently started erroring:

500:  {"error_description":"The server encountered an internal error trying to fulfill the request","error":"ServerError"}

I know this isn't a refresh token issue because feeding a bad token on purpose triggers

400:  {"error_description":"The request has an invalid grant parameter : refresh_token","error":"invalid_grant"}

I'm pretty sure the rest of the request is formatted correctly because the "authorization_code" request still works. Anything that I should be looking into, or is this an Amazon issue?

Hi Amit,

Thanks for your help. I was mixing up my access and refresh tokens while persisting them to disk (typo, hah!). If I pass my access token as a refresh token it causes the 500 internal server error. Perhaps returning an invalid grant parameter (like when i mash on my keyboard) would be more useful.

Hello,

This is the response I have received from LWA support team.

"Hi there,

This indicates the access token server endpoint encountered an internal failure, which likely to be intermittent. I would first ask the developers to try again.

Also, if they can continuously reproduce these issue, plz ask the developer to provide:

Time stamps when they made failing requests.
The clientID that they used

Then LWA dev team can help track down the requests in our logs."

Can you provide us information accordingly, if you are still stuck in this issue ?

if it helps you debug the server error, my client id was "amzn1.application-oa2-client.863cf538324c4ca1bf1739195fbc6dce"

Hi, i am using the following code

@IBAction func amzonLogin(_ sender: Any) {

LoginWithAmazonProxy.sharedInstance.login(delegate: self)

}

// The login request succeeded and the user is now authenticated via LWA

func requestDidSucceed(_ apiResult: APIResult!) {

switch(apiResult.api) {

case API.authorizeUser:

print("Authorized")

LoginWithAmazonProxy.sharedInstance.getAccessToken(delegate: self)

case API.getAccessToken:

print("Login successfully!")

//loginBtn.isEnabled = false

//logoutBtn.isEnabled = true

case API.clearAuthorizationState:

print("Logout successfully!")

//loginBtn.isEnabled = true

//logoutBtn.isEnabled = false

default:

return

}

// The login request to LWA failed

func requestDidFail(_ errorResponse: APIError!) {

print("Error: \(errorResponse.error.message)")

}

When getAccessToken method is called it is returning an error

("The server encountered an internal error trying to fulfill the request").???Why

Pls help

\

AIMobileLib.getAccessToken(forScopes: ["profile"], withOverrideParams: nil, delegate: delegate) is the code for getting access token
