Hi,

Answer

Hi SantoshPanda,  
  
I assume you're following this guide:  
https://docs.aws.amazon.com/greengrass/latest/developerguide/opcua.html  
  
Please attach the logs from your lambda, if any. Those logs are stored at:  
\[Greengrass-Install-Location]/ggc/var/log/user/\[region]/\[customer number]  
  
Please also attach your index.js file.  
  
Thanks,  
Keagen
