Create engine failed, error code: -7 , with Fetching the Token scene

[Nelsonlala]

hi, i am trying to use the dynamic fetch token from the server feature in the scene from joinChannelVideoToken file,

following website: https://www.agora.io/en/blog/connecting-to-agora-with-tokens-using-unity/

I set up the token server in Heroku (following : https://github.com/AgoraIO-Community/agora-token-service)

then i replace the token base with the updated server url. and set up app id.

then when i run the scene in the unity editor, the error is shown below. anyone can help me with this

Create engine failed, error code: -7
UnityEngine.Debug:LogError (object)
agora_gaming_rtc.IRtcEngine:.ctor (string) (at Assets/AgoraEngine/Scripts/AgoraGamingSDK/AgoraGamingRtcEngine.cs:241)

-7 means the sdk has not been initialized properly. could you pls show us your minimal reproducible project or relevant source code?

hi, I redownload the SDK and it seems fine now.

But I am following the website: https://www.agora.io/en/blog/connecting-to-agora-with-tokens-using-unity/

to use the dynamic fetch token. however, I would like to use this feature in the WebGL platform.following this sdk: https://github.com/AgoraIO-Community/Agora_Unity_WebGL

and i try the dynamic token example scene there and it's not working (token client that one ). then i try to implement the script in this sdk to the WebGL sdk but now it's become so messy.

and facing two errors:

1. Assets\API-Example\tokenchannel\TokenChannel.cs(67,13): error CS7036: There is no argument given that corresponds to the required formal parameter 'newToken' of 'TokenChannel.FetchToken(string)'

2. Assets\API-Example\tokenchannel\TokenChannel.cs(126,20): error CS7036: There is no argument given that corresponds to the required formal parameter 'options' of 'IRtcEngine.JoinChannel(string, string, string, uint, ChannelMediaOptions)'

ANY suggestion to solve the problem!!

@Nelsonlala I didn't notice your issue until today. Hope this can still help. For any WebGL issue you should go to the WebGL repo to post there. We have built an example on how to use token in its included API-Examples. Please take a look.
