I am using flutter\_zoom\_videosdk: ^2.5.10 in my flutter app to integrate zoom for video calling. But getting error as given below:  
onError, error: ZoomVideoSDKError\_Session\_Invalid\_Param  
D/ZoomVideoSdkDebug(23476): onSessionLeave, reason: ZoomVideoSDKSessionLeaveReason\_BySelf  
Steps I followed

1.I refered official documentation for zoom video sdk for flutter to build app

2. I have created app on marketplace. From their I have used client id and client secret to generate jwt token required for joining session. For testing purpose I have generated jwt token from official auth link of zoom.

3.But while testing I am getting onError, error: ZoomVideoSDKError\_Session\_Invalid\_Param

I have given complete logs details as below:  
D/ZoomVideoSdkDebug(23476): SDK initialized successfully  
I/flutter (23476): JWT: eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJhcHBfa2V5IjoieGV3MVBsU2FjSUdwN0dONVVVUSIsInRwYyI6InJvb20tMTIzIiwicm9sZV90eXBlIjowLCJ2ZXJzaW9uIjoxLCJpYXQiOjE3OTA5MjU3NzYsImV4cCI6MTc5MDkzMjk3Nn0.ROjt8ojmvcz7LjSTPA3FEcHgfaRyitBeFwi6qX-8Yqs  
D/ZoomVideoSdkDebug(23476): Session details: - session=“room-123” user=“Ram k” role=0  
D/ZoomVideoSdkDebug(23476): Join Session successfully  
D/ZoomVideoSdkDebug(23476): onError, error: ZoomVideoSDKError\_Session\_Invalid\_Param  
D/ZoomVideoSdkDebug(23476): onSessionLeave, reason:ZoomVideoSDKSessionLeaveReason\_BySelf

Hi @Ganesh1 Could you try testing your credentials against our flutter quickstart app: [GitHub - zoom/videosdk-flutter-quickstart: This is a sample application that demonstrates how to use the Zoom Video SDK in a Flutter app · GitHub](https://github.com/zoom/videosdk-flutter-quickstart)

From there, we can verify if this is an implementation issue or an issue with the way your generating your JWT.
