[Bug] EULA acceptance validation fails.

[RokeJulianLockhart]

The Problem

Despite having re-accepted the EULA, ¹ I'm unable to download UE:

...because each attempt returns: ²

<epic_asset_manager::tools::epic_web> - [ERROR] - Failed to parse EULA json: expected value at line 1 column 1

How To Reproduce

1. Sign the eulacheck.

2. “Revalidate” in EAM's GUI.

Expected Behaviour

I should be able to download UE.

[Sectimus]

This fixed it for me

[RokeJulianLockhart]

@Sectimus, like that, I was also prompted to re-accept the EULA. However, it doesn't appear to have worked. If there's a way for me to capture useful network traffic for the application, I'll do so. Unless I've misunderstood. In which case, a screencast would be of use.

[that404nerd]

Doesn't fix it for me. Still says the same thing.

[Boc86]

Same issue

[danieleagle]

I'm having the same problem.

[Narsell]

Also having the same issue here. Has anyone been able to fix it?

[PolyCatDev]

Same here. Apparently it's some issue with parsing the received JSON since I get error <epic_asset_manager::tools::epic_web> - [ERROR] - Failed to parse EULA json: expected value at line 1 column 1

My guess is that the app is probing a dead end point

[amoshydra]

The code HTTP POST to https://graphql.unrealengine.com/ue/graphql

{
  Eula {
    hasAccountAccepted(id: "unreal_engine", locale: "en", accountId: "__my_account_id__") {
      accepted
      key
      locale
      version
    }
  }
}

Epic-Asset-Manager/src/tools/epic_web.rs

Lines 140 to 146 in b8b36b8

	let query= ["{ Eula { hasAccountAccepted(id: \"unreal_engine\", locale: \"en\", accountId: \"", id, "\"){ accepted key locale version } }}"];
	map.insert("query", query.join(""));
	match self
	.client
	.post("https://graphql.unrealengine.com/ue/graphql")
	.json(&map)
	.send()

However this URL will now return 410 Gone.

Maybe the URL has changed. I see a related change at https://github.com/derrod/legendary/pull/713/files. But that PR contains the store URL that might be different from this one.

I don't get CF's challenge page when changing to this URL. But I am having trouble running the graphql command

If I set UA as UELauncher..., I get this error:

{
  "errors": [
    {
      "message": "GraphQL operations must contain a non-empty `query` or a `persistedQuery` extension.",
      "correlationId": "...",
      "stack": null,
      "status": 500
    }
  ]
}

I believe this UA is incorrect. This non-empty query error seems to be a generic error.

If I set UA as EpicGamesLauncher..., I get this error:

{
  "errorCode": "errors.com.epicgames.common.authentication.authentication_failed",
  "errorMessage": "Authentication failed for /api/public/agreements/unreal_engine/identities/__my_account_id__",
  "messageVars": [
    "/api/public/agreements/unreal_engine/identities/__my_account_id__"
  ],
  "numericErrorCode": 1032,
  "originatingService": "com.epicgames.eulatracking.public",
  "intent": "prod"
}

This looks more relevant. But I am not sure how to pass the authentication
